This appears to be that a leftover task/callback happens as we're trying to tear down the test. RenderFrameHostImpl seems to be taken in a bad state.

->wjmaclean because this is possibly related to  crbug.com/291278 

This also failed in https://build.chromium.org/p/chromium.fyi/builders/Site%20Isolation%20Linux/builds/9490.

Seems concerning, given that this is an old test.

It has been failing very consistently (not flakily) on "Linux Tests (dbg)". First failure: https://build.chromium.org/p/chromium.linux/builders/Linux%20Tests%20%28dbg%29%281%29%2832%29/builds/29708

(it may still be a flake, so worth looking at previous changes too).

Looked through, not clear suspect. There is https://chromium.googlesource.com/chromium/src/+/730669d119402a19dca92b5c0cc50bb6ff89172f from lazyboy@, landed on previous run, I assume it impacts this test?

I'm going to run this locally and see what's happening as I don't have a hint on how my change can affect this.

The failure is interesting:
