VLC opts for screen:// in playlist not respected

[onthewings]

I tried using a playlist to save my desktop screen capture settings (screen-width=400 and screen-height=400, i.e. a 400x400 crop of the top-left corner):

When I open the playlists (both m3u/xspf), VLC didn't use the supplied option but used the default.
I tested with VLC 3.0.6 64-bit on both Windows 10 and macOS 10.14.

Is that a bug?
