vaadin-grid always has last row focused

for some reason the last row in my grid is focused when i load data, the selection array is empty, i even tried to remove the vaadin-grid-row-focused class attribute on the row...it unhighlights it correctly but when scroll away then back it is focused again.  The only thing i can do is click a row on the grid then the behavior goes back to normal and is ok.

any suggestions on what i may be doing that is causing this behavior?  I tried to replicate in a simple example and could not.

any ideas would be appreciated

Hi Jason, can you tell how do you load the data to the grid?
