Outer gap value of 16 makes windows get smaller rather than move

[leviport]

In non-tiling mode, if I set an outer gap value of 16 and inner of 4, hitting Super + Enter and attempting to move the window with only the arrow keys, the window tries to resize very strangely instead of just moving. Hopefully this gif shows it happening

Some more info: I can get the same thing to happen with an outer gap size of 32, but I actually get log output. When the blue window selector is at its smallest size, any arrow press gives me this:

value "-2.000000" of type 'gfloat' is invalid or out of range for property 'width' of type 'gfloat'

I also noticed that setting gaps to 16, then 32, then back to 16 just continues to make the window smaller as if it's applying outer gaps multiple times. This is only in free-float mode though.

I can't think of a good reason for gaps with floating windows. It doesn't go together.

The drop-down menu is only for auto-tiling. If that might be confusing, perhaps we should grey out options unless Tile Windows is active. @maria-komarova thoughts?

I agree, we might need to grey out the gap. I can't think of the use case for gaps in floating mode either. Shortcuts - yes but not gaps.

Going to close this and track disabling gaps in floating mode here in #104
