It looks like there's negative heap unclassified in memory-report-TabsOpen-0.json.gz in a content process.

This content process contains the following pages:

│ ├──52.46 MB (32.07%) ++ top(https://docs.google.com/spreadsheets/d/1jT9qfZFAeqNoOK97gruc34Zb7y_Q-O_drZ8kSXT-4D4/edit#gid=1115838130, id=33)
│ ├───4.49 MB (02.74%) ++ top(https://www.apple.com/macbook-pro/, id=49)
│ └───2.13 MB (01.30%) ++ top(https://www.paypal.com/myaccount/summary/, id=65)

That process has the entry:

└──-0.93 MB (-00.57%) ── heap-unclassified

Is one of these pages new to the TP6 page set? If I had to guess, the Apple page might be doing something weird graphicswise that is hitting a bug in the WebRender memory reporter.

This is still a guess, but maybe it is related to fonts? It looks like there are quite a few fonts here, and I think we've had some recent WebRender memory reporting bugs that involved fonts. It looks like there are a number of both Apple and Google fonts in there.

None of them are new, but of course anything could have changed in the site contents between the recordings. Is there anything else we can do to help with this investigation? I could try to determine the site that's causing the issue by process of elimination if that's useful?
