I have created a dojo http://dojo.telerik.com/IkaQa with an example spreadsheet that is full size (no scrollbars) that is larger than the screen. If you scroll down to the bottom of the spreadsheet using the window (document) scroll and then select a cell (row 200) it will jump to the top of the window. This only happens in Firefox, IE and Edge, works correctly in chrome. I am currently using a spreadsheet in this fashion in a product. I have been able to add event listeners and override this issue in IE and Edge but for some reason the click event in firefox registers as a double click only. This is a big issue for me and I will open a ticket if need be, any help would be appreciated.
