I have a grid with a checkbox selection model and tall cells due to custom html renderers. The problem is when any cell is clicked the grid jerks because the selected cell is scrolled into the focus.
Here is a fiddle with the problem, try scrolling the table manually halfway first and then clicking on the cells to see the grid jumping (it's not consistent, might need to try a few times): https://fiddle.sencha.com/#view/editor&fiddle/1vma
Is there a way to disable row focusing on click, or disable row selection on click if thats the root cause (so you would have to use checkboxes to select rows).
