Closing one of grouped mingw64 (git bash) instances causes loss of focus

Hi. I'm a developer and recently started using your app. It is pretty great. I noticed few bugs though. Nothing critical but rather annoying.

Pre-conditions:

- Windows 10 Pro

- Groupy version 1.32

- Intalled Git bash - https://git-scm.com/downloads

- Possibly relevant Groupy config options:

--- "combine if possible"

--- "always group windows when moved on top of each other"

--- "instantly group windows"

--- "use whole window" is off 

--- "only group windows of the same app" is off

--- "automatically group identical windows" is on

Scenario 1:

1 - Open one or more other irrelevant apps (just for the sake of them being there)

2 - Open few git bash instances (mingw64.exe), group then either manually or automatically

3 - (Optionally but not necessarily, group them along with one or more explorer tabs)

4 - Switch to one of bash instances

5 - Close it

Expected result: window with tabs keeps focus, any of the remaining tabs gets activated

Actual result: random app gets a focus

Scenario 2:

1 - (Same)

2 - (Same)

3 - Group them along with one or more explorer tabs (this produces different results)

4 - Switch to exporer tab

5 - Close one of bash instances

Expected result: (same)

Actual result: one of:

1 - whole window disappears, although remaining apps keep running and can be found in the taskbar;

2 - window remains but a line with tabs disappears.

In both cases, it takes few seconds for Groupy to get back to normal.

Please let me know whether you can reproduce this or not. I can help with debugging this if needed, just let me know.
