I have a strange problem with ToolTips in WPF (.NET 6): My ToolTips are showing only for a few milliseconds and then close again. It was working like normal a while ago, but I can't find out exactly what change to my application has broken the tooltips. At least I can say that I didn't mess with the ShowDuration property. Is there any possibility how I can find out why a tooltip is closing? I tried to catch the ToolTipClosing event and add a breakpoint, but there doesn't seem to be any helpful information in the ToolTipEventArgs.

It's a bug in the .Net6 WPF release: https://github.com/dotnet/wpf/issues/6289
