--- FAIL: TestLookupHostCancel (0.02s)
    lookup_test.go:947: LookupHost("invalid.invalid"): failed with unexpected error: lookup invalid.invalid: Temporary failure in name resolution
FAIL
FAIL	net	43.759s

See previously #31950, #25694.

It's not clear to me whether this indicates a problem with the builder, the test itself, or the code under test.

This test has a fix CL out for review, and is a source of recurring failures on at least one builder. Marking as release-blocker via #11811.
