Live Youtube videos not playing with HTTPS Everywhere 3.4.5 (FireFox)

Playing a Live Youtube video on Firefox with HTTPS Everywhere caused the player (Flash, not HTML5) to display a "Please stand by" message. Disabling the Youtube ruleset did not fix the issue and only disabling the addon itself allowed live videos to be played. I have encountered this bug on two machines: A Windows machine and a Linux machine both running Firefox. Playing Live Youtube videos on Chrome with HTTPS Everywhere did not cause this issue.
