Bug: Desktop dark mode setting is does not appear to be passed through to webapps to autodetect

[Pxtl]

I'm running Linux Mint in Cinnamon.

When I try to open MS Teams in full Firefox, it properly inherits the Cinnamon dark mode configuration. However when I open my MS teams webapp in Web Apps, it is in light mode.

I'm using LibreWolf but I had to modify about:config for it to parse properly

privacy.fingerprintingProtection.overrides = +AllTargets,-CSSPrefersColorScheme

I think the bug is on Mozilla's side not Mint perhaps
