Voice messages break when two composers are shown (main + thread)

[grimhilt]

Steps to reproduce

1. Start recording a vm either in a thread's composer or in the main composer.
2. Stop this recording.

Outcome

What did you expect?

I would expect to have a vm standing in a thread or in the main chat, waiting to be send, with only one "send button" setup to send this vm.

What happened instead?

Even with the other composer empty, both "send button" are active with the note "send a voice message". If I click the send button with the empty composer, I have an error in the console.
