WP Media Gallery incorrecy showing "alt text"

[minddoodle]

Hi

I have discovered that when a user completes the following workflow the WP gallery is incorrectly showing the "alt text" and "title" field attributes.

1) create post
2) upload image
2.1) specify "alt text" image text e.g. "hello world"
3) update/save post
4) open Media --> Library
5) select the image created in step 2
6) inspect the properties of the image
ERROR: the "alt text" property is blank!

NOTE: when the post is rendered to HTML it does show the correct alt text (as per 2.1)

Hi @minddoodle, welcome to WordPress Trac! Thanks for the report.

Unless I'm missing something, this appears to be the expected behavior:

• When you're adding an alt text in the Image block settings in the post editor, it only applies to that specific block in that specific post.
• If you'd like the alt text to be saved with the image, it can be done in two ways:
  • By going to Media Library and editing the image there.
  • By adding an alt text in the "Attachment Details" sidebar after selecting an image from Media Library in the "Select or Upload Media" modal when editing a post.

I'm closing this ticket because the issue was already reported on the Gutenberg repository, ​issue 8941.

If you want to address how this works specifically in the block editor, please add comments on that issue. You also could join discussions about more general improvements to the interface for setting alt text, as well as how alt text is saved, on ticket #47456.
