Rapid focus switching in valo

I am using Vaadin Grid with valo theme
Theme : Valo with $v-animations-enabled: false;
Grid has has 40 columns including generated columns. 2 of these columns is editable. (Not generated columns)
Double clicking on row make the 2 columns editable. Navigating columns using TAB is enabled in the grid.
If the tab is switched very fast from one end to other end, focus becomes locked in the editable columns and the 2 columns starts switching each other with no control for user. Reloading the page is the only option to stop with focus switching. Video attached.
This happens when you navigate the columns using tab from one end to other and backwards faster.

Any suggestions or solutions ?
