Here is how this page looks on mac, multiple browsers: https://demos.telerik.com/blazor-ui/grid/grouping

Notice that the columns are misaligned.  I believe this is because the scrollbar isn't rendered on a mac if it is "disabled" (there is nothing to scroll). 

Probably the best solution would be for it to render like this on all browsers, but have the columns line up (get rid of the spacer in the end of the header row) as the 'empty' scrollbar is not attractive :)
