I'm trying to test the accessibility of the grid detailTemplate on https://demos.telerik.com/kendo-ui/grid/detailtemplate , namely keyboard navigation.
Honestly, I don't even know where I am. I know when I'm focused on the button "Edit in theme builder" (it's barely visible, but visible), and when I press tab, document.activeElement points to the first table header ("Last Name"), but it's not visible at all. Then I keep getting lost.
I have tested it with all sass-based themes and the less-based Material theme.
