Plan step 36's handoff listed six behaviours no browser test exercised
yet:
- FieldsTest: <x-select>'s open list uses the customizable picker
(appearance: base-select) where the browser supports it, drawn as
M3's 48px-row menu.
- CommunicationTest: a two-line snackbar's action stays on the
title's row from 600px, only wrapping under it below that
(toast.css's [data-md-toast-wrap]).
- ActionsTest: a disabled menu item reached by the keyboard withholds
its state layer (interaction.css's [aria-disabled="true"] rule).
- DataTest: a paginator's page step shows md-focus-ring's outline on
keyboard focus, alongside its already-tested 48px target.
- CommunicationTest: a transient rich tooltip stays open 1.5s after
focus leaves rather than closing at once (rich-tooltip.js's
LEAVE_GRACE_MS).
- ActionsTest: an xs or sm group segment takes a press at its 48px
edge, past its drawn size, now that the target comes from the
shared md-touch-target class rather than a rule of its own.
