In library editor tree selected and currently opened items aren't very distinct on MSW

There are still some rough edges in the footprint editor tree view. One is that, at least on Windows, the currently selected (clicked with mouse) and the currently opened items aren't easy to distinguish from each other. The currently opened footprint and its library seem to be both selected. If I select something else with mouse there are three items which look like selected. I have attached a screenshot. Without prior knowledge, who can tell what is actually selected and what happens when I click the RMB somewhere?

I suggest that the currently opened footprint and its library are marked active by some other means, for example with bold font and/or some extra mark.
