YouTube – How to Load a Playlist

When I search for something on YouTube, and there's a playlist among the search results, I click that list, and it's "loaded" (that is, there's the playlist bar at the bottom of the window, where I can manage the videos; the videos will play one by one automatically; and the rest of the page looks according to the default YouTube theme). This is exactly what I want.

Now, if I specifically go to some person's channel, click Playlists, and click the playlist I want, how do I "load" that playlist in the same manner? It just won't load, it will keep me on the person's channel page (looks of which I might hate), and the videos from the playlist will just sit there, in the column to the right, and won't automatically play one by one.

Currently my workaround is:

• Go to the channel.
• Find the playlist I want.
• Copy the name of the playlist into the search box. Search.
• Find the playlist in the search results and click it. Voila, it's "loaded."

I hate doing that every time.
How do I load (in the described way) a playlist I manually selected at someone's channel?
