Bug on mobile browsers when filtering movies

To replicate:

- In any web browser on an Android device (probably on iOS too), visit the imdb page of a director or actor

- Under "Credits", click the first icon that looks like a filter and then in "See also" click "by Rating"

- You get a list of movies with a section at the top to filter them. As soon as you tick a checkbox such as "Feature Film", the movies list disappears and the only way to make it reappear is to set the browser to Desktop mode and then replace m by www in the url
