> I tried going with ForceSet() instead of using hidden attributes but i didn't find a way to reset the cached value in that case (would probably need to set the accessor function again, but it's internal to the v8 generated file), and a way to invalidate the value is needed for the history.state thing.

Using GetHiddenValue()/SetHiddenValue() makes sense to me.

(FYI: Rather, I would object to use ForceSet() here. We are planning to move DOM attributes from a DOM object to a JS prototype chain (https://bugs.webkit.org/show_bug.cgi?id=75297), but ForceSet() makes it difficult (or impossible?). I cannot move MessageEvent.data from a DOM object to a JS prototype chain because it uses ForceSet()...)
