Cannot scroll page after completing episode

Hi,

I usually try to read any comments on the video's, so after completing a video I scroll down the page to read those. However, I noticed the page does not scroll anymore after completing a video since last weekend or so.

I had a quick look at the CSS in the browser developer tools. With completing a video the CSS class dialog-scroll-locked is added to the body element (to show the episode complete dialog). However it is not removed when clicking 'Cancel' to prevent the page from going to the next video. If I remove the dialog-scroll-locked CSS class manually, I can scroll the page again.
