Bug 36589: Advanced cataloging - restore the correct height of the clipboard

A simple direct fix for the height of the advanced editor's clipboard,
which is a <select size="10"> that's currently cut down to the height of
one thick line by CSS intended for non-multiple, non-sized selects with
dropdown menus.

Test plan:
1. Set the pref EnableAdvancedCatalogingEditor to Enable
2. Cataloging -> Advanced editor
3. Note the Clipboard is a single line tall
4. Apply patch, shift+reload Advanced editor
5. Note the Clipboard is ten lines tall
