[FxOS 1.3] Tweet window not scrollable

[Ryuno-Ki]

When composing a tweet, it sometimes happen, that the lines are so long, that they expand the window.

When the first lines gets out of view thereby, there is now way to reach it again.
I'd like to have some kind of scroll mechanism here.

To get an idea, look at the screenshot posted in #56.
You'll notice, that there is no handle or scrollbar to reach the first line.

I have the same problem on Firefox OS 2.5
