The test closed the showcase's standard sheet straight after resizing
the window and sampled its exit, but the sheet has no transitions until
the view settles, two animation frames after Alpine starts, and WebKit
had often not run those frames yet: the sheet closed at once, as it is
meant to while settling, and the test read that as a missing exit. It
failed in Safari when run on its own on 2.1.0's code as well. The
sampling script now waits for `data-md-drawer-settled` first.
