What is the current behavior? (You can also link to an open issue here)
This is a reoping of PR 1016.
A regression in the drawing guide in the geometry-input component assumes that we are drawing circles. It doesn't work with any other style.

What is the new behavior?
It works with other styles as it should. I'm not sure the demo provides a way to test that easily but I did test it.

@cbourget how to test/validate?

[cbourget]

You need a <igo-geometry-form-field> with [drawGuide]=true. This will render a number field input with a radius value, in pixels. When drawing a circle with that radius value is visible around the cursor. This the drawing guide.

I'm not sure if the demo has a geometry field that would allow you to test that. On my end, I tested it in the FADQ app.
