I find issues after the current update of Windows EDGE to 25.10586.0.0.The font icons from "Courier New" are not visible after the update.
The font defined within an iFrame gives an error as specified below.
CSS3116: @font-face failed cross-origin request. No Access-Control-Allow-Origin header.
CSS3120: No fonts available for @font-face rule
The source of font format is within the same origin and not a cross-origin.
PS: This was not an existing issue before the update.
Thanks & regards,
Hanif Kukkalli
