OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 120. Event dispatching on disabled form controls is being changed in Edge to improve compatibility with other browsers and to improve the developer experience. With this change, MouseEvents get dispatched on disabled form control elements. Exceptions for this behavior are click, mouseup, and mousedown. Some examples of the new events are mousemove, mouseenter, and mouseleave. This change also truncates the event path of click, mouseup, and mousedown when they’re dispatched on children of disabled form controls. These events aren’t dispatched on the disabled form control or any of its ancestors. Note: This new behavior might break some websites. If this policy is enabled or left not set, the new behavior will be used. If this policy is disabled, the old behavior will be used.
