I have a RadEditor with RenderMode="Auto" as in html code below ( there is no code-behind for this page since no server-side code is being executed).
When I switch to mobile view on Chrome Dev tools then I see the RadEditor render in mobile mode. But, if I click on Find and Replace icon of RadEditor, then it results in a JavaScript error as shown in attached screenshot. It seems that RenderMode="Auto" doesn't work as expected.
Do you know of any workaround that can fix this problem? I am using R2 2020 version of ASP.Net AJAX controls. I need to use RenderMode="Auto" since that is needed for seamless skinning of all controls on the aspx page.
