Scale input field - trying to change step to 0.5 crashes the form

You won't see much in the video but I'm trying to change 1 to 0.5 at which point the whole form becomes unresponsive. When you see me moving around with my mouse, I'm trying to click on different fields:

I understand that adding 0.5 steps could be considered a feature request, but trying to do what is not possible should not crash the app.
