Exception thrown at line 513 in XamlProperty.cs

I'd love to get some help solving this (see linked PR). I'm pretty sure, that the fix proposed in XamlProperty.cs is correct, but the functional behavior of the demo application is still strange and doesn't look correct IMHO. If anyone could verify and point me to the right direction, that would be great.

Maybe your fix in XamlProperty is correct (I'll take a look), but to fix this correctly I think you need to fix ApplyTransform in ModelTools.cs

The RotateTransform Extension does already use this, the Skew Extension not, so this needs to be fixed. And this function needs to be changed so it loads and keeps existing Transforms when applying a new one

Thanks @jogibear9988 for the hint. Good to know that I may be on the right track. Looking forward to tackle the rest of this issue in the next days.
