Editing poll options via drag and drop

Fixes presentation invisible box appearing if presentation is hidden

This is a workaround that shaves off some edge cases around wrongfully done camera reconnections and outbound cameras getting stuck in the UI even though they arent being shared anymore

Problem: setReconnectionTimeout was being called in the first candidate generation to set the negotiation/reconnection timeout up. That caused some browsers or specific scenarios (mainly envs without STUN) to establish the negotiation (playStart) before generating any useful out-of-band candidates (relay). That would cause the timeout to be set AFTER it is supposed to be cleared due to success (playStart), making the webcam drop after a while

So I moved the setReconnectionTimeout call to a safer spot: right after the first negotiation requisition goes out to bbb-webrtc-sfu

Reduce logging volume and payload size, perf

There's some scenarios that video errors triggers multiple toast notifications
that don't have any mapped defined message feedback so they all drop to the default
permission error. This leaves the impression that something is broken at the toast
container.

Since those messages don't bring up much information about the problem we can avoid sending
them until we don't have a more informative one to notify the user.
