Wallpaper doesn't span on lock screen

[solomongrundy6]

Using Solus Budgie, I use a 3840x1080 wallpaper that spans across two monitors - it's two 1920x1080 wallpapers stitched together into one image. I used the 'spanned' option and it properly displays each of the two 1920x1080 wallpapers on each monitor this way.

This does not seem to work on the lock screen. There's a separate option in dconf to handle this, instead of org.gnome.desktop.background.picture-options and .picture-uri, the lock screen uses org.gnome.desktop.screensaver.picture-options and .picture-uri. However setting these the same way as their .background counterparts does not behave the same way, it puts the entire 3840x1080 wallpaper on both monitors. (In other words, it's no longer spanned, it shows the entire thing once on monitor A, and again on monitor B.)

Wondering if this is a reproducible bug or if my particular setup is just weird somehow. For the time being I just set a different, single 1920x1080 wallpaper on zoom for both windows, but if possible I'd like it to behave the same as my regular desktop. If budgie-screensaver is going to be replaced or otherwise obsoleted by the transition to Magpie or Wayland, I won't be heartbroken if it ended up not getting fixed.

budgie-screensaver is going to be nuked from orbit with the translation to Wayland, and we should be able to acommodate this use case with its replacement.

That's what I figured, but thought I'd check.
