Native/Chromium clients bypass Windows audio effects (Equalizer APO) on microphone input, web app in Firefox does not

Observed behaviour

Fluxer native app: raw mic, system audio effects (Equalizer APO) are bypassed entirely.
Fluxer web app in Chromium (Chrome/Edge): raw mic, same bypass.
Fluxer web app in Firefox: mic correctly passes through the system effects filter.

Reproduction steps

In App mic settings: All toggles for mic settings in custom/disabled, except noise suppression which is set to standard
On Windows, apply Equalizer APO on a capture device and add an effects (eg. RNNoise).
Confirm the filter works correctly system-wide (test in Windows, Discord, or Firefox-based apps).
Open Fluxer native desktop app and speak while triggering background noise.
Open Fluxer in a Chromium-based browser and repeat.
Open Fluxer in Firefox, join a voice channel, repeat.
Compare whether the APO filter is audibly applied to your mic in each case.

Details

Expected behaviour The mic signal that reaches the voice channel should include any system-level audio processing applied via Windows standard audio effects pipeline (APOs), consistent across all Fluxer clients, same as how the native Discord client and Firefox both respect these effects.
