Flickering tooltip text

[drguildo]

Thanks for making this; it's very useful.

When I have a card selected (i.e. the image is displayed) and I mouseover the "High Stakes" Missable Cards by Quest entry, the tooltip text flickers on and off so quickly that it's impossible to read.

I think it might be because when a card image is displayed, it pushes the Missable Cards section further down the window vertically, and so there isn't enough space to display the rather large tooltip beneath the mouse cursor (at least on my 1920x1080 desktop), and when it's displayed above the mouse cursor it causes the flickering bug.

I think this might be caused by this bug in Avalonia.
