When using the chrome accessibility panel to inspect the filter operator button, there is no accessible name or title (hovering over the button does not give a tooltip with the name of the button).
The clear filter button does have an accessible name and title.
Please correct the filter operator button in order to meet WCAG Accessibility Standard 1.1.1 (Non-Text Content) and 4.1.2 (Name, Role, Value)
The Accessibility Support page for Kendo UI for Vue Native Components (https://www.telerik.com/kendo-vue-ui/components/accessibility/accessibility-compliance/) incorrectly implies that the Vue Native grid has keyboard navigation support. The page seems to be referring to native components as seen by the breadcrumb and the introduction text.
All of the items in the list except for the grid are linked to the Vue Native component. The "grid" item is linked to the Vue Grid Wrapper (https://www.telerik.com/kendo-vue-ui/components/grid-wrapper/keyboard-navigation/).
I believe there's already a (unplanned) feature request out there to add keyboard navigation features to the native grid, but in the meantime, please remove the grid from this page as it does not currently support full keyboard navigation.
