Comment 4

[Alexandre Poirot [:ochameau]]

Attachment: Bug 1901788 - [devtools] Consider iframe target as resuming on destruction.

The throttling prevents the removed iframe from emitting a THREAD_STATE resumed resource.
Instead, we should consider the related TARGET_DESTROYED event and resume on target destruction.
