Comment (by afercia):

 Looking at this after some time. While the current patch fixes the
 position of the checkmark, radio buttons and checkboxes still don't scale
 with text zoom (see screenshot attached below).

 Re-defining all the metrics using `em` (or `rem`) like in
 [http://adrianroselli.com/2017/05/under-engineered-custom-radio-buttons-
 and-checkboxen.html this technique from Adrian Roselli], would allow these
 controls to scale together with text when zooming only text (e.g. with
 Firefox) or when increasing the default font size from the operating
 system settings. Is there already a ticket for this?
