I had the same problem and I was using nightly build version of nvim, I had to upgrade from NVIM v0.11.0-dev-492+g0cdeb06db to NVIM v0.11.0-dev-1321+gfe1e2eff06 to resolve the issue.

I also tested on NVIM 0.10.2 and I don't see the problem either, so I guess you only see this if you are using an old unreleased/development version of nvim 0.11.0-dev

I see now you said

This happens on latest master, not on releases.

well, it seems resolved NVIM v0.11.0-dev-1321+gfe1e2eff06
