RE: making page visibility a property of document instead of top level browsing context

Yes, a change in behavior can be described as breaking compatibility. It’s really an example of a change in behavior that would generally be more beneficial (e.g., power savings) than hurtful (e.g., don’t expect applications are relying on that behavior). Since it’s still a hard problem to solve, I’m not advocating that we fix that example, I only used it as an illustration.

Why do you think it doesn't break compatibility?  It clearly does.  The question is whether anyone is relying on the current behavior...
