User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20170921191414

Steps to reproduce:

I have a container (870px large) in a bootstrap dialog.
In this container, an AUDIO element with CSS : width 100%
In FF 56 55, the style applied. Now, no more... The style is ok in Chrome / Safari


Actual results:

The width is always 870 px, but visually no : it is 270px


Expected results:

The width must be 870px

which is bug 1391791.  Jared, can you take a look at this?  (Ray is away at the moment.)  I'm guessing this change is not intentional.

Let's just close this as a dupe of bug 1397486. I don't see what makes them different.
