It’s been a while that this question was first answered, but I’m facing a similar issue.
I’m using a self-hosted instance and the search query URL doesn’t open the issue directly. It’s usable as the only listed issue is the one being searched and it’s one extra click from the actual page I’d like to link to. Is there any plans to implement the RESTful URL to reach the issue directly? I can’t understand how this hasn’t been requested and prioritized until now. Maybe I’m looking at Sentry with the wrong expectations in mind?
