Fix initiative effects renaming losing focus when set to 'Active and hover'

[rexy712]

Initiative effects collapse when the mouse is not hovering over that entry. When editing an effect name for that entry, the effects would collapse when the mouse exited the parent entry even if the input box had focus.

Initiatially I tried to do this without hard coding separate 'mouseOver' and 'focused' statuses, something like showEffect: { index: number, showCount: number } where the showCount would increment once for each event that asked for focus and decrement once when something released focus. But doing this, I ended up finding some edge cases where the effects would become stuck expanded and other entries could not become expanded. Due to this, I fell back on tracking the variables separately.

This fixes #1767
