@typescript-bot cherry-pick this to release-4.6

typescript-bot · 2022-05-03T19:31:30Z

Heya @DanielRosenwasser, I've started to run the task to cherry-pick this into release-4.6 on this PR at 56b4f68. You can monitor the build here.

typescript-bot · 2022-05-03T19:38:09Z

Hey @DanielRosenwasser, I couldn't open a PR with the cherry-pick. (You can check the log here). You may need to squash and pick this PR into release-4.6 manually.

DanielRosenwasser · 2022-05-03T19:50:44Z

Really? You couldn't cherry-pick a one-line change? 🙄

DanielRosenwasser · 2022-05-03T19:52:29Z

I'll cherry-pick the squash commit manually.
