Add headroom to the navigation performance test

Quick fix is fine but also we should use 📌 Add PerformanceTestTrait::assertMetrics() so it is easier to write performance tests Active in this test - it was the one performance test that didn't get converted in that issue.

Thanks for that pointer, @catch. Let’s see what we can do to make this stable again.

Per Slack, catch is okay to commit this now and do the conversion in a follow up. I or nicxvan will open that follow-up momentarily, but catch only has 29 minutes to connnit this m, so here’s a quick RTBC. There’s a pipeline in the linked issue that shows this change allows that to pass. This is a trivial change. Ready!

Thanks,

Committed/pushed to 11.x and cherry-picked to 11.1.x, thanks!
