I think once it is merged, may be worth to have this in Aurora, since snippets are going to be rewritten better to give them stable document contents (yes, wouldn't be hard to workaround this, but no reason to not avoid that).
> snippets are going to be rewritten better to give them stable document
What exactly does this mean with regards to this bug?
snippets can modify css, for example when they changed the background to black for a day in the past. They may try to do that on "container" and get different results across versions.
I actually forgot a comma in that phrase, "snippets are going to be rewritten, so better give them"
