When the keyboard_navigation
plugin is enabled while displaying the resource chart on a page, clicking on a task in the timeline grid that is outside the visible range triggers the scrollbar to move left and right. This results in an error in the browser console and causes the scrollbar to become unresponsive.

Clicking on the “Development” and “Test” tasks causes errors and renders the scrollbar unresponsive.
