[BUG] Left side bar with playlists is not hidden even if hid

[DarkMoe]

To reproduce:

1. Hide the left bar, the ones with the playlists.
2. Start clicking on the left edge, where the playlists would be if they weren't hidden, near the center-top section but always the leftmost area.

If done properly, a playlist change will occur, which is a little bothersome
