There's a race condition that may cause a client crash whenever a
video-provider's unmount procedure is run, but its signalling websocket
is undefined. The WS's callback handlers are re-assigned without
checking for the socket's availability, causing an unhandled TypeError.
The WS may be undefined in a couple of scenarios, e.g.: unmouting before
the socket was successfully set up, unmounting while a reconnect is in
place etc.
Check whether the socket exists before accessing it in video-provider's
componentWillUnmount routine.
The client may crash whenever a emoji rain animation is triggered, but
the interactions button element cannot be located. This happens because
the button coordinates are fetched without checking whether the element
exists.
Get the coordinate fetching method to return null if the
interactionsButton element cannot be located, and ignore the emoji rain
action if that is the case. Whenever no valid coordinates are found, log
an warning so we can track this and figure out what's happening with the
button.
Fix a few typos in the getInteractionsButtonCoordinates method.
When a sendrecv peer acts as the answerer, gUM is only called _after_
the remote offer is received. This is fine, but the error handling runs
different in that scenario in a way that eventual gUM errors are treated
as negotiation errors, leading to inconsistencies when surfacing the
error to end users.
If a peer is acting as answerer and is a transceiver, acquire the local
streams _before_ actual negotiation so that gUM errors are surfaced
correctly (and we spare uneeded negotiation steps).
Audio exit toasts are fired in some redundant situations, e.g.: when the
error help screen is toast.
Change the logic a bit so that it's only fired when the audio help modal
won't be shown, i.e.: when audio had succesfully connected.
- Fix almost the entire video-provider component typyings. Leaving some errors because the component depends on a lot of code which is not in typescript yet. Any attempt to fix them may cause problems.
