Long press works poorly on IPadOS (and probably IOS).

The code supports long-press on a card in hand to see details of the hints given to a card. This works fine with a mouse. But when playing on iPadOS, it worked very poorly. It generally tried to select the text (number) of the card, and give me an IOS context menu for Copy/Share/etc. The closest I could come to showing the hints was to long-press the corner-mark.
