 possibly #50210

 If adding a Gallery via Gutenberg, if a file is dropped onto the core
 media library  the first upload succeeds as expected. If a second Gallery
 is added and another image dropped on the core media library this uploaded
 freezes and an uncaught exception `Uncaught TypeError: Cannot read
 property 'text' of undefined` in the `wp_includes/js/media-views.js file.

 To replicate:

 1. Go to Posts > Add new.
 2. Add a title.
 3. Add a Gallery block.
 4. Click on Media Library inside the Gallery Block, add two photos.
 5. Enter the gallery on to the page. The photos appear. All is fine.
 6. Add another Gallery block.
 7. Click on Media Library in the Gallery Block again,
 8. Drag a photo onto the Media library to upload it.
 9. The upload bar shows 15%-ish done, but then just hangs. Nothing is
 shown on the far right side. If I click on the photo upload, I get the
 name of the image, so the Media library is only partially not working.
 10. Using the x on the upper right to close the Media library and opening
 it again, just brings up the same frozen upload.
 11. Drag another photo into the Media Library, upload also hangs.
