Thomas De Schampheleire:

When reviewing code, the green review icon/button that allows you to add comments for a specific code line only appears after hovering over the line, with a short timeout after that.

If you hover over the line numbers, one would expect the same behavior but no review icon/button appears. This is not intuitive and should be fixed.
