This appears to have been the case for a few weeks now for me... On both Edge and Chrome, the first item in a set of radio buttons cannot be selected unless you click below and to the right of the radio button by a wide margin.
All other radio buttons (other than the first) appear to work fine.
Attached is a video clip showing the issue. You can't see when I'm clicking, but I'm trying repeatedly to select the first Radio button by clicking on the button or the label. Only when I click well below the label and to the right of the button does it finally select.
