Slow rendering after dialog close

I have simple SfGrid with about 600 rows and two columns - without virtualization and paging.

I have also simple SfDialog - binded to field IsVisible.

When i set IsVisible = true, displaying the dialog takes a long time and the console shows a message like "

[Violation] 'click' handler took 594ms"

So I add "DataGrid.PreventRender();" and the dialog opens quickly


But when i try close the dialog (without any logic etc.) I see something like "[Violation] 'click' handler took 1396ms"

And when I add "DataGrid.PreventRender();" this is faster but still very slow: "[Violation] 'click' handler took  993ms"


ps. Without any data in DataGrid,  
everything goes very quickly.
