Steps to reproduce:

1. Use Firefox
2. Add a Wiki portlet to a page
3. Edit the frontpage.
4. Add a very long, continuous text in one line, for example:

thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,thisisaverylongline,

Actual Result: The border of the editor has been pushed out of the screen to the right.
Expected Result: The border stays where it is, and a horizontal slider appears (like in Chrome or in case of the Blogs portlet for example)
