Instructions box doesn't readjust sizing for screen available area

In the module for learning localstorage, step 11, the instructions box doesn’t adequately resize for the screen area. Worse, the example code within the instructions box runs out of the box borders but there is no way to see the text.

Since this is not related to code we are writing, I have provided a screenshot so you can see the issue.

The box could be expanded to the empty middle area just like the code above (not shown) and the user editable box expands. And within the example box, a scroll bar needs to display if necessary.
I’m running on a MacBook, Google Chrome, and zoom at 80%.
