Tab renaming

Platform: Mac

Application Shell: 3.5.42

Unable to rename a duplicated tab by adding to the end of it, ie Timeline 2, Timeline 3, Timeline Grouped, Timeline (whatever).

I duplicated the Timeline tab, selected Group.
Selected Rename (tab) and the name “Timeline” turned into a small text field with the name highlighted, which filled the text space.
Tried to click after the “e” to add " 2" but it closed and remained as “Timeline”.
No matter how many times after that I selected Rename, nothing happens so it is stuck with the same name as the tab it was duplicated from.
Note: Yes, I can rename if I type to replace the whole name.

Answer the following questions, if possible:

  • Are you able to reproduce this bug reliably? YES
  • Can you make this bug happen with a clean timeline file? UNKNOWN
  • Does it only happen with a specific timeline file? NO
