EddyEditor: trile rotation mode keep resetting when changing the trile

As reported by maYayoh on Discord:

> Im in "Rotate: Copy", then pick another trile, and it resets to "Rotate: Fixed" (also doesn't show the face and that you can scroll to change it anymore)
> 
> It used to keep the Rotation mode, which was better imo (especially when using the "Copy" and "Random" modes)
> The "Fixed" mode not showing which way is facing is a bit of an issue i think
