GitHub pull requests accept reacji just like comments, issues, etc. But currently Bridgy seems to not recognize reacji in reply to a pull request review permalink like:
https://github.com/w3c/PWETF/pull/143#issuecomment-651990278
And returned this error:
2020-06-30 20:05:17.817455 Please remove the fragment #pullrequestreview-440206392 from your in-reply-to URL.
Expected result: apply the reacji to the pull request review.
Label: publish.
