Something is putting focus on the listview items. Should be easy to fix, but we need to identify a clear repro to say it's fixed.
Repro.
See Screenshot:

@ryanbodrug-microsoft I don't know the details of the issue you mentioned here. Please add some more background info.
@ryanbodrug-microsoft is this still repro? We need repro steps/guidance
I dont' have repro steps. Somehow the results list gets put into focus. A boarder appears around the listviewitem, and you can no longer type into the textbox. Udit reported seeing this in the bug bash as well.
This still exists for the mix UWP/WPF mode. We should wait until we do the full WPF flip
I found a repro. Right-Click and the press spacebar.
We just released 0.18.1 which will have this fix included in it.
