Rubrics criterion with many levels (individual points) controls get truncated on right side when editing and unable to select truncated levels when grading. User must zoom browser window out as horizontal scroll bars not displayed

using Moodle 2.2 (build 20111209). with the standard theme

To Reproduce the issue

Using the rubrics feature of m2.2, create a new advanced assessment rubric definition and for any criterion keep adding levels (points) eventually the "add level" button will be pushed out the right and out of view, you have to zoom out to see it but if you keep adding levels you have to zoom out so far as to be unable to read the text. I can fit about 13 or 14 levels with no detailed description in each level just a basic text.

Attached screen show shows 4 criteria with differing points but user unable to view right side controls to add/remove levels as they have been pushed off the view and horizontal scroll bar not displayed
Is there a way to have the content wrap around or force the browser horizontal scroll bar to show instead of having to zoom out for what is really an issue of width?
