Let a rich tooltip linger after the focus leaves too

Plan step 36. The rewrite moved the rich tooltip's pointer-leave grace
from 200ms to M3's 1.5s — kept: the reference gives plain and rich
tooltips the same 1.5s, and ACT-25 names this file's 200ms. Its header
claimed the same for the focus, which still hid the bubble at once; the
focus now leaves on the same 1.5s the plain tooltip uses, and the skill
says so. The stylesheet header no longer cites chip.css and fab-menu.css
for a pulled-back actions row neither has.
