After the Windows update on Tuesday, October 30, you can no longer effectively use the touch screen to sign in Chrome or Edge (on an MS Surface). It does still work in Firefox. Touching within the signature area draws a dot, but dragging your finger just attempts to scroll the page or navigate away from the page. It is as if the press-and-hold behavior does not trigger properly in the signature area.
Signing does work with a mouse click-and-hold or with the surface pen/stylus click-and-hold (holding the side button while you draw).
