--- Comment #78 from Travis Leithead [MSFT] <travil@microsoft.com> ---
I'm sympathetic to the memory problem, but we have to balance web compat
against any mitigation we take to alleviate leaks.

For instance, Edge is currently very aggressive at countering leaks (in iframe
navigation scenarios only), but we pay a cost for a large number of broken
websites that expect to keep access to certain "leaked" data. You could argue
that our leak-breaking logic (which is very old and not originally intended to
fix these described leaks anyway) is not the best/right approach, and would
agree with you, but it has at least given us some insight in the potential
side-effects.
