Window: Fix incorrect logic in dragging code

These `if`s used to be early returns and were improperly inverted in
c199a84.

This is why our integration tests were no longer able to dismiss
notifications by dragging them off-screen, because the tests were moving
the mouse perfectly horizontally, so no drag event was ever emitted.
