Change Details

``` (Luke) was unsure if the code sufficiently avoided caching a time-too-new rejection, so wrote this test to check it. It looks like despite only exempting BLOCK_MUTATED, it is still okay because header failures never cache block invalidity. This test will help ensure that if this ever changes, BLOCK_TIME_FUTURE gets excluded at the same time. ``` Backport of core#22120.
