Looks like this checks that the API is not behind a prefix and we are still behind a prefix.

Bug 1336399 is about removing mozPreservesPitch. I'm not sure if "New wpt failures" bugs are renamed, but making this clearer about how it's about implementing would be great.

Oh, and unprefixed preservesPitch was shipped in Chromium 86:

mozPreservesPitch has been marked as deprecated and aliased to preservesPitch in the attached patch so that we can gather usage data before we remove it completely. For complete removal, please see:
