Files is Nautilus, developed by GNOME. It is likely that is either an upstream issue, or was an upstream issue. We used an older version in order to provide desktop icons support in Budgie, as noted in numerous places across our bug tracker, and a new implementation is currently in progress. Marking this as invalid as there are no actionable items for this, any fix would need to be upstream in Nautilus (and likely isn't an issue in the first place) and we're holding our Nautilus back anyways.
