wl-radio throws error when name has "." #85
Description
If the name attribute of the wl-radio has a . character, such as name="my.name" (or and character that breaks CSS query) then the radio throws an error:
DOMException: Failed to execute 'querySelectorAll' on 'DocumentFragment': 'wl-radio[name=my.name]:not([disabled])' is not a valid selector.
Perhaps the radio should perform some escaping on the name.
