SharePoint 2013 : 'Scroll to Top Search Result Page' OOTB functionality has stopped working

Problem / Situation

'Scroll to Top Search Result Page' OOTB functionality stopped working on search result page.
We have enterprise search center with customized branding (master page and page layout).

Analysis

• In search result web part checked the property "ScrollToTopOnRedraw" (after export search result web part) and it is set to 'True' (default).
• Tried the solution described in blog but no success in hand
• Now we have analyzed that this could be a problem of our customization in search template

Solution

1. Export search result web part and set “ScrollToTopOnRedraw” property option to true

2. Update search result display template "Control_SearchResults.html" template and add “ctx.ClientControl.set_scrollToTopOnRedraw(true)” function at the top of Srch.U.shouldAnimate(ctx.DataProvider)) if condition.

   <div id="Control_SearchResults">
   ctx.ClientControl.set_scrollToTopOnRedraw(true); 
   if (Srch.U.shouldAnimate(ctx.DataProvider))
   {
    Srch.U.hideElement(ctx.ClientControl.get_element());
    ctx.OnPostRender = function(){ Srch.U.animateResults(ctx.ClientControl, ctx.DataProvider.get_userAction()); };
   }
   

3. If step 2 not worked for you then use JavaScript "window.scrollTo(0, 0);" method rather on place of "ctx.ClientControl.set_scrollToTopOnRedraw(true)" function.

4. <div id="Control_SearchResults">
   <!--#_ //JS method for scroll to top issue
   window.scrollTo(0, 0); 
   if (Srch.U.shouldAnimate(ctx.DataProvider))
   { 
    Srch.U.hideElement(ctx.ClientControl.get_element()); 
   ctx.OnPostRender = function()
   { 
    Srch.U.animateResults(ctx.ClientControl, ctx.DataProvider.get_userAction()); 
   };
   }
