General Lag on Vaadin Grid 8 Item Selection

Hello,

I was wondering if someone had insight on how to highlight a row immidiately after a click on an item. It appears that on the Vaadin demo web application, https://bakery.demo.vaadin.com/#!product-admin , there is also a slight half to a full second lag upon the clicking of an item to the highlighting of the item. Is there a way to improve performance of the animation response?

Currently, on the application I’m working on, the ItemClickListener does work that takes on the order of around 30 ms, and the SelectionListener takes about the same, and combined with the lag of the item highlighting the grid almost feels unusable for production.

Thank you.
