Trying to add a feature in our application where a menu has a grid which the user can click to remove an item from using an action column. If a row is removed, a dom exception is thrown, and it seems there is a change of focus when that row is removed and focus is sent to the application viewport.

Here is a very simple reproduction of it in a fiddle:

We are using ExtJS 6.5.3 Classic toolkit with the Neptune Theme. Tested on Chrome on Windows 7.

Is there any thing we can do to get this fixed with an override or setting?
