jwplayer increases height during video playback on Safari
I'm facing an issue when playing a video on Safari.
To give some context, I'm using a MacBook Pro macOS Sierra Version 10.12.6 and I have Safari Version 10.1.2 installed.
The issue I'm facing is that whenever a video plays in Safari, the height of the jwplayer increases. Additionally, scrubbing forward or backward also increases the height of the jwplayer. Has anyone encountered this?
Attached is the link to where this is happening:
Any help / advice is greatly appreciated!
