Empty topic field

[r4mp]

If the topic field is empty, it is still possible to click the "send"-button, which results in an infinit spinner, but without really sending the message.

I haven't been able to reproduce this so far: for me, pressing Send when the topic field is empty results in the posted topic being the string "(no topic)".

• What version of the app are you using (under Settings → Diagnostics), and on what OS?
• Do you know what version of the Zulip server you're connecting to?
• Can you still reproduce this? (It may have been a transient connection issue.)

This looks like it may be addressed further in #3743? @ray-kraesig

This is, indeed, very likely a combination of #3743 and #3731, as described in the latter. (Thanks!)

Closing in favor of those, since the former has an active PR.
