Media items, which have already been uploaded, disappear when the upload dialog box is closed and then opened again.

[shamayel007]

I followed the following steps and got this error:

1) Freshly created a new WordPress site.

2) Created a new page and opened it in the block editor

3) Added a new gallery block

4) Clicked "Media Library"

5) Uploaded new images

6) Uploaded 20 images

7) Closed the dialogue box and opened it back up.

8) Selected a few images and clicked "Create a new gallery"

9) After it went to the "Edit Gallery" window, I closed it by clicking the cross button

10) Clicked "Media Library" again to create the Gallery block

11) Selected photos again and clicked "Create a new gallery"

12) When it again went to the Edit Gallery window, I clicked "Add to gallery"

13) Shows "No media items found", even though I have a lot of images uploaded.

Here are my setup details:
i) OS: Ubuntu 20.04.5 LTS
ii) Using Local by Flywheel
iii) Web server: Nginx
iv) PHP Version: 8.1.9
v) MySQL: 8.0.16
vi) WordPress: 6.1.1
vii) Browser: Opera

Shows "No media items found" even when a lot of images are already uploaded.

Reproduction Report

I have been trying to reproduce the issue, and probably we need to clarify the expected result and behaviour. The behaviour, which I got, is also not clear to me.

Environment

• OS: macOS 13.1
• Web Server: Nginx
• PHP: 7.4.1
• WordPress: 6.1.1
• Browser: Chrome 109
• Theme: Twenty Twenty-Two

Active Plugins: none
(I used Local to build a clean WordPress environment).

Actual Results

• Go to create new page.
• Insert Gallery block.
• Click Media Library.
• Upload 3 JPEG images.
• Choose 1 image and click "Create a new gallery".
• Close the popup by clicking X.
• Click Media Library in the Gallery block -> you are in "Edit gallery", which is empty (I would expect it to be empty).
• Click "Add to gallery" in the left side menu -> you see Media library with 3 uploaded images.
• Choose 1 image and click "Create a new gallery".
• Close the popup by clicking X.
• Click Media Library in the Gallery block -> you are in "Edit gallery", which is empty (I would expect it to be empty).
• Click "Add to gallery" in the left side menu -> you see Media library with only 2 uploaded images.
• Choose 2 images and click "Create a new gallery".
• Close the popup by clicking X.
• Click Media Library in the Gallery block -> you are in "Edit gallery", which is empty (I would expect it to be empty).
• Click "Add to gallery" in the left side menu -> you see Media library which is empty.

I suppose this is the problem.

• However, now close the popup by clicking X.
• Click Media Library in the Gallery block -> you are in "Edit gallery", which is empty (I would expect it to be empty).
• Click "Add to gallery" in the left side menu -> you see Media library with 3 images.

This ticket needs more info from the reporter, as this bug seems to be inconsistent. I was also having problems reproducing the another bug you reported 57488. Which also happens when you upload images through media library on the gallery block. I'm inclined to think this is an issue with the media library modal as a whole or this only happens when accessed through gallery block. But this definately needs to additional investigation.

Media: Reset gallery modal state when abandoning a new gallery

## What?

• clear the transient gallery-edit, gallery, and gallery-library selections when the media modal closes during a new gallery flow
• add a QUnit regression that covers closing an abandoned gallery before insertion

## Why?
The gallery add state excludes attachments already staged in gallery-edit. When the modal is closed before the gallery is inserted, that staged selection leaks into the next create-gallery flow and can make the media library appear empty.

## Testing

• php vendor/bin/phpcbf --standard=phpcs.xml.dist src/js/media/views/frame/post.js tests/qunit/wp-admin/js/media/post-frame.js
• php vendor/bin/phpcs --standard=phpcs.xml.dist src/js/media/views/frame/post.js tests/qunit/wp-admin/js/media/post-frame.js
• npm run grunt -- jshint:corejs
• npx playwright test --config tests/qunit/playwright.config.js
• npm run typecheck:js

I picked this up because the ticket describes a concrete core behavior or edge case that remains relevant in current WordPress. The proposed change is intentionally scoped to the ticket and is submitted here for code review, with the technical discussion remaining on this ticket.
