Crash

Moving the cropping handles in the Insert Frames dialog (Insert.xaml), shown below for reference:

results in unexpected behavior that sets the dimensions to extraordinary values

which can actually crash once it represents infinity in floating point. It gets here fast; I got it naturally i.e. I was not trying to replicate bugs.

To Reproduce
Steps to reproduce the behavior:

1. Click Load, choose a frame
2. Click Media, add another frame that knowingly does not match the same height
3. Click the bottom cropping handle and drag it downwards just a bit, then wiggle the mouse in place
4. Observe the dimensions run to infinity very quickly

Expected behavior
Cropping handles should move normally, of course. None of this craziness :p

Desktop (please complete the following information):

• OS: Windows 10 Home
• Version 19045.5247
• OS and Monitor Resolution match, 1920 x 1080 native

Sidenote

There are several issues with this dialog. It's just very hard and confusing to use, almost everything it does with the cropping handles is surprising. I don't know if other behavior I found is a bug or not, but it would crop the image size as well in the new frame when I attempted to move a handle once, (it reflected a new size under "Image Size") and there's no undo/redo for it.
