We could avoid this relatively easily by using an out-of-band tree (much like the reflow tree that we had before the reflow branch landed). This is what I propose in https://bugzilla.mozilla.org/show_bug.cgi?id=479655
I guess I just worry about the complexity and overhead of maintaining that separately from the DOM.
(Another advantage such an approach might have is that we'd have more room for storing the various types of restyling we might want to do, if we want to differentiate more cases in order to optimize them.)
It looks like we have 5 bits free in mFlagsOrSlots. It looks like you only need 3 or 4 for this. If we need more data we could use node properties. Or perhaps we could use two bits in mFlagsOrSlots for "needs restyle" and "descendant needs restyle", and have a node property with more data for nodes that need restyle.
