fix: Double clicking in any corner while the overlay is enabled, bypasses it.

[GabuTheDev]

Double clicking in the middle of the enabled overlay is handled just fine, but I've discovered that in the very top and bottom corners of each side, they are not. My cursor somehow bypasses it, double-clicking past the overlay and interacting with the game itself.

What amazes me is that clicking does nothing, it's only the double-clicking that creates the issue.
Another thing to mention is that osu receives only one click, meaning on double-click, first is handled but 2nd escapes the overlay.

As asked by Cherry on the discord support server, here are the videos, but uploaded on youtube:

Top Left Corner	Top Right Corner
Bottom Left Corner	Bottom Right Corner

Actually, it doesn't have to be a corner (at least for me).

Notice how the cursor expands whenever I double click (and it stays that way) and doesn't leak any more mouse clicks until I hide the overlay editor and press a mouse button.

It's even worse in osu!(lazer) - every mouse click leaks except for the scroll wheel.
