publish give loop when foget to save

[onno-timmerman]

We experience sometimes a loop when the following happen.

1. start translating something by clicking edit.
2. forget to click on save after you edited
3. click on publish a popup will appear that you have unsaved things are you sure
4. click no and then click on save
5. you will notice the publish icon will spin for a while now

wagtail/wagtail#9956 would solve this everywhere in the UI. (adding for reference)

@zerolab feel free to give this a test against Wagtail main now - the progress button work has been done.

Hopefully it works better for this use case now.
