Bug Description

When placing an input or textarea element inside a ui5-timeline-item, the text cursor does not respond to keyboard arrow keys. Typing and deleting characters works as expected, but pressing the arrow keys does not move the cursor within the text field.

Affected Component

ui5-timeline, ui5-timeline-item

Expected Behaviour

Arrow keys should move the text cursor left, right, up, or down within the input or textarea, as with any standard text field.

Isolated Example

Steps to Reproduce
