Hi - our product uses RadMenu. With the recent release of FireFox 62, they have completely deprecated Mutation events and give us the following error:
Use of Mutation Events is deprecated. Use MutationObserver instead.
Which drills down to this specific line in the 'telerik.webui.webresource.axd'
Line 16890: N.addEventListener("DOMAttrModified",this._onMozillaParentVisibilityChangeDelegate,false);
I have attached screenshots.
This translates to our RadMenu being unresponsive to user clicks.
How can we address this? Any help on this would be greatly appreciated!
