[Linux Mint 22] Software Manager/Sources GUIs are incorrectly themed.

I'm using the Sweet-Ambar-Blue-Dark theme (downloaded from gnome-look) and this is my system information:

System:
  Kernel: 6.8.0-49-generic arch: x86_64 bits: 64 compiler: gcc v: 13.2.0 clocksource: tsc
  Desktop: Cinnamon v: 6.2.9 tk: GTK v: 3.24.41 wm: Muffin v: 6.2.0 vt: 7 dm: LightDM v: 1.30.0
    Distro: Linux Mint 22 Wilma base: Ubuntu 24.04 noble

1. In the software manager the search button is misshapen and the corners of the body are rounded when they shouldn't be.
   
2. The update manager's "downloading" pop-up is light themed despite the theme being a "darker" one.
   
3. The software sources is light themed as well.

Just to cover bases I switched to another dark theme (the built-in Mint-L-Dark-Aqua), and neither the update manager's pop-up nor the software sources are light themed:


So this is an issue with the Sweet theme and not with cinnamon or the GUIs themselves.

Looks like bb6b6e5 fixed the software manager issues, the only remaining issues are the GUIs that are incorrectly light-themed despite a "darker" theme being selected.
