Inline tag shows PR requiring review as mergeable

I noticed that the inline tag shows that a pull request is mergeable even if merging is blocked due to awaiting reviews.
For example, the currently open PR in this repository is #98 - it is mergeable as it has no conflicts with the base branch, but it is not mergeable by the author until it's approved.
I'd love the plugin to distinguish these two states. I'm not sure though if it's a bug or a feature request.
