@shcheklein Please don't put fix-2684 - to the PR name, issue reference in the PR comment is enough, no need to make the PR name even longer. Same with commit name.

PR name - not sure why it matters at all.
commit name - if it's not in the description information is lost after merge, right? (commit <--> ticket)?

Not really, it still stays in the squashed commit message.
