TelerikPanelBar Accessibility issue on 200% width of the screen (keyboard navigation)

The TelerikPanelBar component is using Right and Left arrows on keyboard to opening and closing each tab. 
https://demos.telerik.com/blazor-ui/panelbar/keyboard-navigation

When the page is zoomed to 200%, it gets a horizontal scrollbar, which is normally controlled with the left and right arrow keys on keyboard. However, these keys are assigned to opening and closing the TelerikPanelBar component, which makes it impossible to scroll the page horizontally while we have Tab on TelerikPanelBar. Is there any workaround that would allow horizontal scrolling with the left and right arrow keys on keyboard at this zoom level? Maybe it’s possible to change TelerikPanelBar behavior and opening and closing it by different keys?

Hello Anna,

By design, our components disable default browser actions for keys that we handle for our own features. Imagine what will happen if a user is navigating in a Telerik component with the arrows and the page is scrolling at the same time. The user may easily end up in a situation where the focused component goes outside the viewport.

Keyboard customizations will be possible in the future. Currently we are working on the Grid as the primary component in the product. Other components will follow afterwards.

Regards,
Dimo
