Translation UI opens additional, possibly unrelated, input and scrolls to it

[stevejalim]

I have a Page with the following fields

• title - CharField
• desc - CharField
• content - RichTextField

The content if the RichTextField was pasted from rendered HTML (literally this public page) and seemed to be accepted fine. The en-US page renders fine.

The page is now marked for translation into French and when I go to manually add those translations, the title and desc fields behave 'correctly' - ie, clicking the button to add the translation reveals an new <input> and it can be saved fine.

When I try to translate the first string/source from the content field, however, the UI leaps down to a separate field (containing a URL, which does not feature in the triggering string) and it looks like that's what's supposed to be translated.

It turns out that the the target string does get its input revealed, but the behaviour of scrolling to an unrelated field and enabling that for translation, too, is masking the behaviour.

Here's a screen recording to show what I mean, plus a follow-up with more detail
