Looks like this is because of duplicate entry of same test with different expectations.

Are you sure this crashes in DumpRenderTree as well as GtkLauncher?

Yes, loading the test case in DRT also causes an assertion failure with the patch.

FWIW, I removed the CRASH line, and added a comment on the PASS pointing to the cross-platform bug that tracks the 'some times asserts' problem.

removed load-defer-resume-crash.html from test expectations since it is going to be fixed in 85159.

How does goBack differ from the history.back()?

Only the difference I see here is history.goback() calls NavigationScheduler first.
