What behavior were you expecting?

Tricky, but notes that refer to an upstream version for which no corresponding version exists, should be ignored. (Usually, this shouldn't happen very often, especially for Opera, where we track a beta and nightly release.)

What version(s) of BCD is the issue present in?

• The current BCD release
• The current version of the main branch

Do you have anything more you want to share?
