`confirm-dialog` is one singleton for every confirmation in the app,
and `wa-dialog` reports its close asynchronously: `open = false` starts
an animation and `wa-hide` arrives after it. So a hide belonging to a
question already answered can land after the *next* question has
opened, and cancel it — the user is asked something, the dialog
vanishes on its own, and the call site is told they said no.
Each ask now carries an id. `close` ignores an id that no longer names
the question on screen, the button handlers pass none (they always mean
the current one), and only the `wa-hide` handler carries one, because
only `wa-hide` can arrive late.
Found by writing two `confirmAction()` tests in one file: the second
could not be accepted at all, because the first one's hide had
cancelled it before the click landed. Reaching it in the app needs two
confirmations close together, which the album page's "Apply tags" makes
possible.
