Replace featured image text isn't visible.

[Necarie]

I'm using a fresh install of WordPress with no additional themes or plugins installed. I'm using the Twenty Twenty-Four theme and the latest version of Firefox.

I imported an xml file to restore posts from another WordPress. There were media files referenced in it that failed to upload, which was fine as I intended to replace the images manually. When I edited the posts to replace the featured images, the featured images option seemed to be missing.

I eventually figured out the option was there, but I couldn't see it because the text on the buttons was the same color as the background. This only happens when there is a reference to a missing image - once I added a valid image, the button appeared as black text on a light background.

It may not seem like a big deal, but it took me a long time to figure out because I'm not familiar with this version of WordPress or where the button was supposed to be. I hope that by reporting it I can spare someone else the frustration I felt - it seems like something easy to fix.

This shows the button where "Replace Image" should be visible, but it isn't.

@Necarie thanks for your report and welcome to the WordPress Trac.
I can reproduce the issue you reported even when deleting from the filesystem a featured image already set. Seems to me this is a clear issue of the new Featured image UI that doesn't take into account missing / broken images.
I will move this ticket to ​The block editor GitHub repository, as all issues related to the Gutenberg editor should be traacked there.
