Describe the Bug

wiki contains this example:

overlays:
  backdrop:
    overlay:
      name: backdrop
      back_color: "#00000099"
      back_height: 100
      vertical_position: top
    plex_all: true

which implies that vertical_position can be used. It's not documented, but is in the example.

However, this:

overlays:
  backdrop:
    overlay:
      name: backdrop
      back_color: "#00000099"
      back_height: 100
      vertical_position: bottom
    plex_all: true

still puts the overlay at the top of the image:

[My test run had the height set to 400, not 100]
