Switch focus and splits don't work when terminal is zoomed

[Felixoid]

Is your feature request related to a problem? Please describe.
When a tab has few terminals and one is zoomed, switching to any direction doesn't work. There are different approaches in different emulators:

• tmux cancels zoom and switch to another pane
• kitty remains zoomed, but switch the pane to the next/previous one

Describe the solution you'd like
I'd prefer tmux approach, when focus change is triggered, it's better to zoom out the current terminal and then switch

Describe alternatives you've considered
Kitty's approach would work as well. The zoom can be preserved during a terminal focus switch

update: the same case is for splits. It seems logical to me to exit zoom mode and split terminal. And the same for tab switching.

I'm working on this. I've implemented a surprisingly clean solution for splits and new tabs. Still working on the 'switch to tab' thing.

As a side note: un-zooming a terminal when there are tabs, makes the background opaque.

Thanks again for the bug report.

Edit: also, the 'move to another terminal' event.
