[Bug] Cannot scrub videos

**Packages & versions**

Media

**Describe the bug**

When showing a video on the display, it is not possible to scrub/seek the timeline because it moves the window. However moving the window whilst a video is playing is sometimes desirable so finding a way to allow both may be difficult.

**Reproduction steps**

1. Start playing a video
2. Try and use the timeline seek on the display window to go forward/back

**Expected behavior**

The window does not move

**Additional context**

This would be redundant if #41 was implemented

Start in the Media display window by reproducing the reported conflict between timeline seeking and window movement while a video plays. Trace the existing handling for the timeline and the window, then confirm that seeking works without unintended movement while window dragging remains available.
