Firefox + Realtime API (WebRTC): voice sessions drop deterministically on the user's second speech turn

We’re seeing the exact same issue. Sessions always drop in Firefox, but work fine in Safari and Chrome. It doesn’t always happen on the second speech turn, but in all our cases it drops within the first minute of the conversation. One Session ID where the drop occurred (I hope that’s the ID you’re asking for): rtc_u0_DensPXCLRPoWm4tBWFw34
