Unit tests with Comments Are Displayed as Uncovered

[allocgator]

In GitHub CI, I'm using grcov to generate raw coverage data and Codecov to view metrics.

I have written unit tests with comments for a few simple problems and noticed that asserts with comments are shown as uncovered. For example, in this and this case, I ran cargo fmt locally then pushed the changes.
In this case, I did not run cargo fmt - pushed the changes directly. Not sure what the problem is here
