Embeddable player: Jumping to another point on the timeline does not work in Firefox and Chrome

Describe the bug

The embeddable player correctly appears on my website. However, when I try to jump to another position in the audio, the player jumps only a little bit forward, not to the desired position.

It does not work in Firefox and Chrome, but in Safari it works well! 😳

Steps to reproduce

1. Open https://gettheaudience.com/e26-audience-by-cold-outreach-marie-martens/
2. Scroll some lines down to the embedded player
3. Click on Play
4. Click on the timeline near 25:00 minutes.
5. The player moves a bit forward, but not until 25:00.

Expected behavior

The player should move forward and backward to the desired position that I clicked on.

Actual behavior

The player jumps only a little bit but not to the desired position.
