Details

Bug 1880262 fixed a case of YSOD that didn't go through the XML parser. We think this wouldn't have shown up in our telemetry numbers because they're triggered from the parser. We should try to add telemetry to detect the case of showing the YSOD to the user, which is actually the thing we care most about resolving.

We're not sure how we'll do this in practice yet, but we have some ideas like detecting when layout tries to create a frame for a parsererror element in a chrome document.
