Mainly trying to solve this failure on #832:

It is safe to commit this! I saw that the new coverage action sometimes fails on the first try, but works the following times

[juliasilge]

This failure is definitely unrelated to your work @olivroy. 👍

There is apparently a new problem with webfakes (which pins uses for testing) on the test coverage PR. I'm going to see if I can figure it out quickly, but if not, I'll merge your PR as is and just live with the test coverage failure for now.

Closing this as we watch for the fix in r-lib/webfakes#103
