Comment 4

[Cosmin Sabou [:CosminS]]

Based on the above retriggers and the changes in Bug 1743020 looks like the leaks in Bug 1772309 turned into these ones. Looks like they leak on content-security-policy/inside-worker/sharedworker-script-src.sub.html
Nika, could you please take a look over this?

(In reply to Cosmin Sabou [:CosminS] from comment #4)

Based on the above retriggers and the changes in Bug 1743020 looks like the leaks in Bug 1772309 turned into these ones. Looks like they leak on content-security-policy/inside-worker/sharedworker-script-src.sub.html
Nika, could you please take a look over this?

Definitely sounds like these are existing leaks which just changed in signature due to the new library being used.

These leaks appear to be related to worker lifetimes around shutdown or similar, so redirecting over to that team to take a look at them.

Comment 39

[Andrew Sutherland [:asuth] (he/him)]

This family of leaks was probably related to bug 1775784, but since the failures went away well before that bug was fixed, it's likely either:

• This signature changed to one of the signatures that were much more egregious but related to bug 1775784.
• This signature was related to changed in the worker script loader. A number of changes landed through 2022-11 that could have aided in the signature disappearing (or shifting).
