Bug is not fixed.

I can confirm this to still happen in 0.70.4. Not sure how to provoke it, it's however gone for the moment if the user reloads the page.
Still happens in 0.71.0-rc.0 as well.
Happend to me on Firefox. Part of the HTML read <textarea class="rc-message-box__textarea js-input-message autogrow-short" style="height: 155px;" autofocus="" placeholder="Message" rows="1" dir="ltr">. Once I go to a different channel the problem is gone. After a restart of Firefox and logging in again to this RockChat, at one point it will happen again.
I just started to happen on my 0.69.2. At least in desktop client.

It still happens in https://open.rocket.chat/

Under some conditions, the width of <div id="autogrow-shadow"></div> was set width: 0 at that time.
Agree it happens sometimes on mobile DM or channels
Any status update on this issue? @tassoevan @ggazzo
@dj301 We did some adjustments in the develop branch version which should fix it.
we changed the messagebox code a lot since this issue was opened, I'm very confident we already fixed it, please reopen if I'm wrong.
