When an e2e test fails in AfterEach, ginkgo "helpfully" adds
a heading in that test log block:
TOP-LEVEL [AfterEach]
/path/to/source.go
Podman Desc Blah
That TOP-LEVEL line screws up our in-page links. Ignore it
both in the heading and in the bottom failure-summary lines.
Add test, including tests for bottom-summary.
