This changes previous layout shift attempt (see #9546)
to account for more valid usecases:
- On the first event that is intercepted we enforce the hit target. This
is similar to the current mode that checks hit target before the action,
but is better timed.
- On subsequent events we assume that everything is fine. This covers more
scenarios like react rerender, glass pane on mousedown, detach on mouseup.
This check is enabled by default, with `process.env.PLAYWRIGHT_NO_LAYOUT_SHIFT_CHECK`
to opt out.
