Content Scripts do not match on the URL query

[Carlos J.]

Safari incorrectly ignores the query string when matching match patterns. Giving the following match pattern:
"https://example.com/*query*"

Safari matches only when the "query" is part of the pathname, not the query string.

It should also match the following URL:
https://example.com/?query=1

Example extension:

This has been tested in Safari 17 and Safari Technology Preview 192. In both no match is made on the URL query.

Carlos, do you know if this is a regression from previous behavior or has Safari always behaved this way?

Thanks for looking into this! I can not rule out this used to work at some point in the past.
