I had a stack of 3 PRs open. I folded B into A, submitted, and went up to C, submitted, which correctly changed C to have A as a new parent. Pull requests for A and C are up and correct, but B is still there in the remote. Is there a way/is it expected for the pull request from B to be closed when folding it into its parent?

currently the best way to do this is to manually close the pr on web, but we are planning on adding a prompt that offers to do it for you!
