Description

Platform

Windows11

Browser

Chrome

Current Behavior

Problem: The timeline playhead is currently rendered outside of the main scrollable tracks area. As a result, when the user scrolls the timeline horizontally, the playhead remains in a fixed position and quickly scrolls out of view, making it impossible to see the current playback position in relation to the timeline content.

Cause: The component was placed in a parent container that did not scroll, while the timeline tracks were inside a nested ScrollArea component. This structural separation caused the playhead and the tracks to scroll independently.

Expected Behavior

Recurrence Probability
