Desktop: Fixes #11485: Fix pressing enter during composition in the title input moves focus

[personalizedrefrigerator]

Summary

Previously, if enter was pressed while in composition mode, focus moved from the title to the note body. This was problematic in the case that enter was used to select a character during composition.

Fixes #11485.

Testing plan

MacOS Sequoia:

1. Set up a composition method.
   • I enabled "Japanese - Romaji" in keyboard settings.
2. Focus the title input.
3. Start composing.
4. Press enter.
5. Verify that the title input is still focused.
6. Exit composition mode.
7. Press enter.
8. Verify that the note body is focused.

I'm closing this temporarily — I can't reproduce the issue if I run the "Testing plan" steps above before applying this change.

Edit: Although I was unable to reproduce this on Linux (Fedora 41/GNOME), I was able to reproduce this on MacOS Sequoia with the Japanese (Romaji) input method. I've updated the "Testing plan" and am re-opening this pull request.

There is also a regression that Ctrl-L, Ctrl-F does not give focus on the search bar, Have to Ctrl-L - click in editor - Ctrl-F to find on page. Is this related to this problem? It is such a habit and annoying when it does not work anymore. Would imagine that Ctrl_F would be a global shortcut to search-menu at the bottom of the screen?

I think this would be a separate issue.

I haven't been able to reproduce this in Joplin 3.2.5 with the default editor and all plugins disabled. I'm testing by:

1. Starting with the Markdown editor in split screen mode.
2. Focusing the editor.
3. Pressing ctrl-l
   • This hides the viewer.
4. Pressing ctrl-f
   • This opens the search dialog.
5. Typing "test".
6. Closing the search dialog by pressing escape.
7. Repeating steps 3-5.
