BUG: Original size of minimized or hidden klotures incorrect
The original size of a kloture is somehow not retained when minimizing or hiding klotures - then restoring from minimized state or hidden state. It looks like some small default is used - or it's the original height from when it was first created.
Indeed, it is only on *new klotures which have not been resized yet. Once it happens, you have to resize it, then it retains. This is likely a missed property assignment on construction. But also a missed property assignment on the actual minimization or hiding.
