The test-case is heavily inspired by: https://github.com/google/brotli/blob/master/tests/testdata/x.compressed.01 Or in words: A metadata meta-block containing `Y` (which should be ignored), and then the actual data (a single `Z`). The bug used to skip one metadata byte too few, and thus read garbage.
