@Pginer-WMF and @jmatazzoni should chime in here, but as far as I understand, this is intended behavior... the conflicts themselves are marked (and soon will be marked with an actual red border) but the other filters remain as-is.

It makes sense, too -- when I look at my filters, I want to immediately see the *reason* why there's no result - so if all filters were greyed out, I would have a lot less chance in solving the issue rather than showing me that filterX and filterY are conflicting, and the rest are okay.

I agree with @Mooeypoo.
There are some combinations that we know in advance they don't make sense, we should surface those cases especially confusing such as the implicit dependencies across groups (e.g., newcomers implying registered users), but we should not be afraid of the user getting no results ( if I search for "red", "cars", "under $5" I may get an empty result in most car rental services, and that's fine).

In the example, the "your own edits" is working well by restricting from the current set the results to only those by you. The issue is that the current set is already empty because of previous contradicting selections.
