Protip: the space between the UI control and the label should be done using padding (or achieved via label nesting) so that the entire area is clickable.

    [ x ]   some long label

         padding here, not margins or gaps

Calling this a "Protip" is generous.

That the combined element has any surface area that doesn't toggle the radio setting is a straight-up bug.

It is laughable for a component this heavily refined to have such a basic usability flaw.
