SonicWall Content Filter doesn't block Youtube on Google Chrome (QUIC)

Issue

SonicWall Content Filter is setup to allow all web access during lunch break time, but block all non-work related websites for the rest of the day. Mostly this works as expected, but some users are able to access Youtube during work hours. This only affects users on Google Chrome browser. Users on Internet Explorer and Firefox are blocked from Youtube correctly as per schedule. What seems to be happening is that once a user accesses Youtube during lunch time, he or she can continue accessing Youtube indefinitely until browser cache is cleared. Restarting Google Chrome, or even computer itself doesn't seem to make any difference.
