I have no text on the estate in hand: Windows 8.1 plus Chrome Version 71.0.3578.98 (Offizieller Build) (64-Bit).
Thanks for the report/screenshot. It has nothing to do with the browser but is a bug in the code that decides how cards are drawn that have non-standard features, like an Estate under Inheritance or cards that are made Treasures by Capitalism.
In your case, I *think* the cause is that you passed the top Estate (from 2 in your hand) to opponent via Masquerade, but the exposed bottom Estate isn't prepared for that. I guess that that passing mechanic may have been overlooked for the overhaul for those special-frame effects that came with Capitalism.
Thank you Ingix. What you write makes all sense. The estate was inherited.
