select change event blocks keyboard navigation Accessibility Checkpoint

Description

select lists cannot be operated from the keyboard if they have a change handler that performs navigation, because the handler fires as the user moves the selection up and down using the keyboard.

Help

Moving through list items using the arrow keys will jump to another page unexpectedly.

Applicable standards

Note: Section 508 Refresh (2017) checkpoints are equivalent to WCAG 2.0 level A and level AA checkpoints.
