Opening a new Tabby instance breaks running Tabby instances layout if they were snapped to corner

[IwishIcanFLighT]

Describe the problem:

When opening a new Tabby instance, any running Tabby instances that were snapped using Windows snap assist will break their layout, change size and move themselves at random position on the screen. Instances that are not snapped or maximized are not affected.

This is particularly jarring if you have multiple tabby instances running on two monitors, all snapped in their corner. Opening a new tabby instance mess all running instances, and you don't know which is what and where it was.

To Reproduce:

1. Open a Tabby instance, snap it to a corner (using the mouse or Win Key + Left/Right Arrow Key)
2. Open a new Tabby instance (either Ctrl + Shift + N or from a shortcut)
3. The new instance opens, and the running instance resizes itself and change position randomly (most of the time it moves itself half outside of the screen it was on).

Tested on Windows 10 22H2 19045.5131 using Tabby 1.0.215.
