It basically just does the same thing the code next to it does with paint phases:

newPhase = (newPhase == PaintPhase::ChildBlockBackgrounds) ? PaintPhase::ChildBlockBackground : newPhase;

(ChildBlockBackgrounds vs ChildBlockBackground is bit subtle)

I suppose the other flags are not relevant for event regions?
