Perform flexbox child hit testing by testing all children atomically

When two child elements of a flexbox overlap (for example, due to
negative margins), the element drawn in the foreground may not actually
capture the hit if the element underneath it is hit-tested in an earlier
phase (e.g. foreground before child block background), despite being
occluded. This is because painting of flexbox children is done
atomically (all phases at once). This change makes hit testing atomic as
well, in accordance with the spec [1].
