Snap apps not follow theme

Prerequisites

• [X] I performed a cursory search of the issue tracker to avoid opening a duplicate issue.

Checklist to make sure the issue is not on your end

• [X] I have made sure that I do not have multiple versions of the theme installed. Only one version should be installed in either ~/.local/share/themes or /usr/share/themes or ~/.themes
• [X] The file ~/.config/gtk-3.0/gtk.css does not exist. (If it does, backup and remove it.)
• [X] I have logged out and in again.
• [X] Dark theme only. I have enabled adw-gtk3-dark in gnome-tweaks AND set the appearance to dark in gnome-control-center
• [X] The flatpak theme is installed org.gtk.Gtk3theme.adw-gtk3 and org.gtk.Gtk3theme.adw-gtk3-dark
• [X] The app I'm having an issue with is an actual GTK3 app and is not coded using another toolkit like GTK2, GTK4, QT, etc.
• [X] I have created a new user profile without any modifications except adw-gtk3.

No one is currently maintaining a snap version of the theme.

Is currently any known workaround?
