Fixed
- Tucked picture-in-picture shook as it slid back in (#576): macOS reports a window's move a
moment late, and Zia read the late part as the window being dragged, let go of the tuck and
tucked it again with a spring. A finished slide now keeps the place it was sent to. - Peeking out from a side, picture-in-picture now reaches the screen's very edge, not the
usable area's (which stops short of it where a hidden Dock waits). The pointer pushed to
the edge counted as leaving it, so it tucked away, and could peek and tuck over and over.
Thanks kcussiefil.
