Resizing of tiled windows should behave like sway/gnome default

[sand-r]

Briefly describe how the feature should work
When resizing tiled windows with super+mouse, the windows should not get resized to be bigger/smaller than the available space on the desktop.

Sway resize:

Gnome default resize:

Gnome with tiling assistant resize:

Explain why this feature should be added
Resizing would be much easier with mouse when windows are tiled.

Unfortunately, that's not really possible. If the user grabs a corner, they will always be able to resize 'tiled' windows diagonally. The reason is that Tiling Assistant and all other tiling extensions can only do fake-tiling. That means we only move and resize floating windows programmatically so that the windows look tiled. However, in the end they will still be floating windows. So the user can resize them freely. It's a limitation of being a GNOME Shell extension.

I guess I could workaround this by 'forcing' (resizing/moving) windows back into their tile once the grab is released. it's not a great solution, but probably the only one.
