Patch

This fixes the bug and clears the maps as it was before the regression was
introduced.

However, I've noticed that the existing (and pretty old) code may have race
conditions. `fetchedMatchedStyles` and` fetchedComputedStyle` are called in
parallel and they modify the same variables. I'll take a closer look.
