[Frederik Braun [:freddy]]

Hi SerbanS,
how sure are we that this is in DOM: Security? From a cursory reading this might also come from DOM Event Handling or JS.
Can you get us a regression range for this leak?

Comment 2

[Serban Stanca [:SerbanS]]

Hello Frederik! I'm not sure on component.. Watching more carefully, I noticed that there are some recent leaks that all have this failure line in common: TEST-UNEXPECTED-FAIL | LeakSanitizer | leak at js_pod_arena_malloc, maybe_pod_arena_malloc, pod_arena_malloc, pod_malloc and on this perspective we had Bug 1711640. Should I open a new bug on this theme?
As for regression range, I couldn't find something relevant, only backfilled and retriggered from first point where I found it.

Comment 6

[Andrew McCreight [:mccr8]]

It looks like we're leaking a ton of stuff, so maybe this is a case of our "ignore all JS engine leaks" ignore listing for WPTs is insufficient.
