Example URL:

Steps to reproduce the problem:
1. use <audio controls> </audio>
2. publish
3. 

What is the expected behavior?
The 'control' bar is very inconsistent between chrome, safari and firefox. Chrome is SIGNIFICANTLY higher. 

This makes simple native <audio controls> un-usuable.

What went wrong?
Chrome controls are nearly twice the height as the controls in other browsers. This makes putting a simple cross platform player into the header of my website impossible - have had to build my own player and it has (other unrelated issues) - this was not historically an issue.

Did this work before? Yes pre May 2018 it was not causing me an issue.

Is it a problem with Flash or HTML5? HTML5

Does this work in other browsers? Yes

Spoke to Jai Krishnan (who i have done some other work with) and he suggested filing a bug report.
