When pasting long text Antidote sends nothing

[dvor]

After pasting long text and pressing "Send" button nothing happens - text just disappears, message is not sent.

This happens not just with pasted text but with manually-written messages if they're too long as well. Sometimes it seems that it doesn't erase the whole message either. A contact of mine had the second half of their message sent to me with the first half cut off.
