Amp-Audio lost tracking icon between last release and this Beta.

Description

When comparing 2307150128000 vs 2307212240000 on a page with amp-audio present, I noticed the position indicator was missing in the Beta Release candidate.

The attached screenshot shows the regular release on the left, and the beta version on the right.

Reproduction Steps

Using Chrome 115 Device Emulator.
Ensure your intended version of Amp is active over here:
https://cdn.ampproject.org/experiments.html

I used this URL to verify:
https://amp.closetfactory.com/blog/closet-factory-made-ashley-hafstead-closet-space-fit-queen/

You might need to scroll down, but maybe not as the amp-audio element is near the top.

Play the audio
Use the middle element to jump forward some minutes
Pause the audio.
Observe the element.
