I saved this as a snippet (under "Sources" in chrome dev tools) and ran it at https://app.codecov.io/gh/[ORG]/[REPO]/pulls?prStates%5B0%5D=MERGED

Script sleeps for 500ms so it can take a while to run. Results log to console.

May need to adjust the sleep amount (go lower if possible) and lines that filter out "bad" (too big of) coverage changes.
