Have a stricter target path match for broadcast messages
Discussion from Slack:
Looks like there is a small issue with how we check the URL for broadcast messages. Right now our target is */issues but the message is displaying on */issues/2313#note_324632148
We're not strict when it comes to matching the regex. E.g for /issues
as target path, we match for /gitlab-org/issues
although there is no wildcard in place. We also also would match /issues/123
which should be more explicit.
