Thanks for the report! This issue should be fixed as part of the next release, and you can try out the fix in the pre-release (go get golang.org/x/tools/gopls@v0.3.4-pre1) now. gopls/v0.3.4 will be released tomorrow. Closing this issue as a result.

Thanks! I'll make sure to try out the prerelease first the next time I encounter a bug, though in this case it wasn't 100% reproducible.
