Round 3 of adversarial review, reproduced live: type an uncommitted edit
into one Variables row, then click a DIFFERENT row's own delete button
without blurring the first. The click's mousedown blurs the edited field,
which commits and triggers a full non-keyed redraw of the whole list
(inspector.js draw() -> node.replaceChildren()) -- destroying the delete
button mid-gesture, so the click that started on it never arrives. No
error, nothing removed, no sign anything happened.
Fixed with the same mousedown+preventDefault idiom this session's own
autocomplete.js already uses for the same reason: stop the browser's
default focus-move (and the blur/commit/redraw it would trigger) before it
can pull the target out from under its own pending click. Confirmed with a
Playwright test reproducing the exact sequence.
