Although given the rarity of this case, I think I could watch for changes and just bail out of the work if that happens.

If I do a .innerHTML conversion back and forth I'll lose the refs. In theory they can be found again but it would require (again) walking the tree and running heuristics on it, which is potentially worse.. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
