When I open an auto-generated CI profile with IPC markers enabled, and then go to the devtools console, I get a flood of

Let's make these warnings developments only for now.

But ideally we want to fix the IPC markers. This warning is due to how we incorrectly try to generate key values for IPC markers while matching them across threads. This is https://bugzilla.mozilla.org/show_bug.cgi?id=1784285
