Keep Comment input box expanded when clicking away

Currently, when typing a comment on a task, the input box expands dynamically as you type. When you click away from the Asana desktop app, the input box collapses back down to 1 line tall.

I’d like at least the option for it to stay expanded when clicking away. I often copy and paste information from other programs into comments and having to re-click on the now tiny comment field each time is troublesome.

Perhaps this could be accomplished by a ‘full screen’ button like with tasks?
