Hi,
There's a problem in the grid using Grouping.
When I resize the the window the grid content starts to move over the left space and goes over the arrow.
this problem happens on your own demo example https://ej2.syncfusion.com/aspnetcore/Grid/Grouping#/bootstrap4 (try resizing the window and you will see)
I need to maintain the size of that column, because I applied a different background color for the .e-groupcaption so it looks bad.
thanks.
