Fix audio content overflow in windows. (#944)

/claim #667

The volume slider in audio element in windows chrome overflows.
Possible fixes:
1. Change the width of audio blocks. (Not suggested, as the width of all
blocks should be consistent)
2. Adjust the audio sub elements, so it doesn't overflow.(IMPLEMENTED)

It's not so straightforward to apply customization to audio tag element.
The best possible way I could find, to make the app look good, is by
hiding the timeline track in the audio. It was showing up very small
anyway(due to block width), so there shouldn't be an issue.
Please look at the before & after videos below.
