The fit overlay is actually touchable

The devlayer is pointer-events: none and every child opts back in; the
overlay never did, so every real click fell through to the plan while
the smoke's synthetic dispatch — which skips hit-testing — kept
passing. The overlay now opts in, the corner handles grew to finger
size, and the smoke performs REAL elementFromPoint hit-tests through
the shadow root so an untouchable overlay can never pass again.
