We are currently utilizing Kendo version 2017.1.118, and I am experiencing some odd behavior in IE11 with tabs and data transferring between the grids.
When you are on tab 1 with a grid, and you dbl click an item it triggers my add function which adds that row to another grid on tab 2. The entire page then loses focus. I can no longer scroll the page, the grid, or even click my other tab unless I click somewhere in the window.
I initially solved this problem by utilizing the hack $("#tab1").trigger("click"); which would force a click. This enabled me to now be able to select tab 2, but for some reason it didn't fully enable focus back to the page, so I was still unable to scroll unless I clicked an element outside of the grid again. Unfortunately firing $("#tab1").trigger("click"); again did not solve the issue.
The main problem is that the page itself becomes unfocused when data is moved from one tab to another tab in IE11. I am not having this issue in any other browser and it only happens in IE11 when data is added to non-selected tab contents.
