First special character always has focus style

[Krisell]

Expected behavior.

Hovered/focused special character has the focus style.

Actual behavior.

The first character per section always has the focus style, in addition to the hovered one.

Steps to reproduce the problem.

See image.

Possible cause

This seems to be an accessibility thing. I can use the arrow keys to move the selected character, and I can use enter to insert it. This is reasonable, but I think hovering any other character with the mouse should remove this style, as otherwise it's no longer clear what enter should do.

Editor version.

Verified in 4.1.0 and above. 4.0.19 does not have this issue.
