I have a problem when write a comment in community forums. Steps to reproduce:

1. Open community forum thread and click Comment below someone's message

2. Switch to Rich text

3. Type few lines of text and then insert a picture

4. Select a picture and try to click Best below it. It is impossible because those buttons are hovered by a panel with file attaching and Comment/Cancel buttons.

See attached example image.

In general, comment composing window is too small. Is it possible to make it larger or add 'Full screen' button there.
