wokwi-potentiometer usability issues when rotated

[urish]

Example: https://wokwi.com/arduino/projects/299392610996322826 (rotating the potentiometer by 142 degrees).

180 degrees seem to be the most confusing.

A good place to start looking is the slide-potentiometer implementation (#63), where a similar issue has been fixed using the inverse of the matrix returned by getScreenCTM().

Fixed!

In Chromium, the potentiometer can be rotated and the glitch is gone.
In Firefox, the potentiometer can no longer be used.

Thanks for reporting! I suspect that the firefox issue is related to #87.
