Close the snap grid if you release the secondary mouse button

[KeronCyst]

1. Have Fancy Tiles set to work with just the mouse; no keys
2. Begin to snap a window by using just left-click-drag and then right-click-drag
3. Change your mind and let go of right-click

Expected result: the snap grid should disappear and the window should stay in the grip of your mouse's left-click as you continue to drag it elsewhere

Current result: Letting go of right-click, even if you're still holding down left-click, causes it to snap to the cursor's closest grid block
