[Enhancement] Improve the new implementation of keyboard focus introduced in 3.5.1

[lef-est]

Description

1. When I click on a word I usually immediately place the cursor in the translation area.
2. As I'm about to start typing, the keyboard focus went to the reading pane.
3. Unaware of the loss of focus, or driven by muscle memory, I still start to type, accidentally triggering some keyboard shortcut, which usually ends in refreshing the whole page.

Problem
Keyboard focus should remain in the translation area if the cursor is already there.

Thank you, I think I have to remove that focus work, it had some good sides but also some bad as you're finding. Thanks for the issue.

I've backed out #459 in the develop branch, so this fix will be launched with 3.5.2, which will likely be out soon-ish. Thanks again @lef-est 👋

Launched in 3.5.2, should be fixed now.
