nowrap in views-admin.css causes text to run off page

While editing the Calendar view with "month" selected the description runs off the page and into the sidebar. The runover seems to be caused by this code in views-admin.css:

.views-display .top .display-description {
font-size: 90%;
font-style: italic;
margin-left: 1em;
white-space: nowrap;

Removing "nowrap" in firebug fixes the runover. Can "white-space:nowrap" be removed from the stylesheet to correct this? I know that an override can be written into the theme stylesheet to get rid of the nowrap, but changing the default would eliminate the need for that.
