YouTube on TVs is cramming ads down your throat even when pausing videos

This is a most excellent place for technology news and articles.
I was casting a video to my shield from my phone and ended up needing to pause for a phone call during an ad roll. Pausing worked fine but the play button on my phone was completely unresponsive after. Thankfully the shield remote still worked, but clearly play/pause during ads is handled differently than during normal videos and something is broken.
