Content Translation keeps a sticky toolbar on top in order to provide access to options regardless of the user having scrolled down the document. The publish button used to be available as part of the sticky header. Currently a regression seems to cause the publish button to no longer be there:
|Before scroll||After scroll|
The publish button should remain on the sticky header in order to be reachable regardless of users scrolling down the document.
(This was tested by translating "Tree" from English to Spanish)
