OK, TIL that [NSCAP_RELEASE(this, mRawPtr);](https://searchfox.org/mozilla-central/rev/4e6970cd336f1b642c0be6c9b697b4db5f7b6aeb/xpcom/base/nsCOMPtr.h#328) does not set the `mRawPtr` to `nullptr`. That means that inspecting memory for ptr values gives false positives hard to detect. So the investigation so far in the pernosco session did not reveal any hot path for now.
