Trying to upgrade a few parts of our codebase now to Ext 5. We see this warning/crash a bit:

Code:
Uncaught Error: DOM element with id schedulergrid-1009-timelineview-2 in Element cache is not the same as element in the DOM. Make sure to clean up Element instances using destroy()
Any explanation of what's going on, new Element caching in place compared to Ext 4?
