The failing test is due to #88112.

[eerhardt]

The failing test is due to #88112.

That was totally a mistake in the test to have different cases. 😊 But at least now we know we have decent test coverage.

[ericstj]

If you wanted to unblock this you could fix that test to have matching case, the have the fix for #88112 add test case(s).

[layomia]

Taking Eric's (St. J :) suggestion - #88067 (comment).
