Plan step 36 review of 9dd527f3. The old view hid a standard sheet's
scrim with `expanded:hidden`; the stylesheet lost that rule (and the
render test lost its assertion), so an open standard sheet at 840px and
up laid a full-window scrim over the page it sits beside, one click from
closing. The rule is back, pinned by a test.
The same review: the scrim now fades out as well as in (with no closed
opacity, allow-discrete only held it at 32% for 200ms and then dropped
it); the modal sheet slides without the fade the old enter and leave
classes never had; it slides from its own edge in a right-to-left
document, which translate-x-full never did; the state rules match the
root's own sheet and scrim, so a sheet nested in an open one keeps its
state; the script's breakpoint is 840px, not 52.5rem, which disagreed
with the stylesheet's px query once the reader's text size grew; and
`width` and the standard sheet's cap are M3's 400px.
