It's not really a stacking context for positioned or stacking context-inducing
children. Maybe paintChildAsPseudoStackingContext, and add a definition of that
in Markdowon & brief comment?

Done.

Added more complete comments to ObjectPainter::paintAsPseudoStackingContext()
and added a "See ..." here.

-    // inline-block elements paint all phases atomically. This function ensures that. Certain other elements
-    // (grid items, flex items) require this behavior as well, and this function exists as a helper for them.
-    // It is expected that the caller will call this function independent of the value of paintInfo.phase.
