Verified the fix on Mac 10.12.6 using latest chrome version #64.0.3255.0 as per the comment #2. Attaching screen cast for reference. Observed that the current page did not get crash upon clicking the <input pseudo="-internal-media-controls-overlay-cast-button" type="button" style = "display:none"> in shadow elements. Hence, the fix is working as expected. Adding the verified labels. Thanks...!! |
