The scroll locking rework that landed with the DxRenderer's partial
invalidation change introduced a deadlock. UIA locks the buffer for
reading before asking it to scroll (which now requires a write lock.)
Scrolling is probably okay to have a little bit of torn state that
might arise from us unlocking the read lock early before triggering the
write lock down the line.
While investigating this, I also noticed that our bounding rects stopped
being viewport-relative (and were instead buffer-relative.) That
regressed with the switch to
