Description

Example https://github.com/winglang/wing/pull/3966

This PR failure was because main was merged into the branch, which caused a snapshot change. The self mutation was applied to the merge queue, but this is a waste of time because mergify already throws away this PR.

The next action depends on the exact circumstance, but generally will require the same update and mutation to be applied to the original PR. At the very least there should be some messaging to clarify that the mergify queue failed for this reason and some possible next steps.
