The current problem:
Somehow, this bug manifested recently in UploadWizard. See the below GIF:
This displays the following incorrect behaviors:
- Clicking add caption removes the above input box
- the new caption field automatically defaults to a language (seemingly based on alphabetical order)
- the trash can icon for the new caption field is offset to the left (moves back to proper alignment if another caption gets added though)
If the user completes submission of a form with these issues, captions entered in the top fields that "disappear" are replaced with the text value of the last entered caption, whatever it is.
