I was just running through the new features of KendoReact 2021 R2 and am very keen to start implementing.
One of my colleagues pointed out that there is an ellipses after each checkbox when using checkboxes under Grid Selection, see https://www.telerik.com/kendo-react-ui/components/grid/selection/#toc-customizing-the-selection). It sees this is the casein MS Edge and Chrome. I use Firefox, so didnt notice it.
Thanks for the new features, keep it up.
