The period-selector arrow-key test called .focus() on the AM/PM radio
right after clicking the field. show() moves focus into the dialog
from Alpine's $nextTick, which Livewire's bundled Alpine defers with a
real setTimeout(0), not a microtask, so the dialog was still closed
when .focus() ran and it silently did nothing, leaving the arrow key
with no effect (step 36 batch: browser tests for the datepicker/
timepicker rewrite).
