You need either a ticket number in the title or the no-title-validation tag on the PR for the Check PR Title task to succeed, btw.

CI seems to be very red right now, probably due to https://www.electronjs.org/blog/ecosystem-node-22/

Merged main to see if there are any actual test failures

Looks like some related test failures around how we used to open the menu and click refresh to perform this action: https://github.com/mongodb-js/compass/blob/870460f23a78a4721518195d994198281098198b/packages/compass-e2e-tests/tests/instance-sidebar.test.ts#L241 @betsybutton let us know if you'd like someone else to take a look or if you're up for it!

@Anemy Honestly, I don't think I'll be able to get back to this soon 😢 Any of you would probably be able to clean it up a lot faster than me. Would be great for someone to pick this up.
