Unwanted icon to the right of "Spring Forces" checkbox

For https://github.com/phetsims/qa/issues/1102 ...

In 1.0, the Spring Force checkbox has no icon to the right of it:

In main, the Spring Force checkbox now has an icon (blue vector) to the right of it:

This seems like a regression, since the purpose of the radio buttons below the Spring Force checkbox is to select the representation of spring force.

@arouinfar To you recall any intentional change related to this, or do you also think this is a regression?

@pixelzoom this looks like a regression to me. There shouldn't be an icon next to the Spring Force checkbox when it has nested radio buttons.

Thanks @arouinfar. Icon has been removed. Closing.
