WPSOLR admin CSS breaking other pages

The plugin is working great but there’s a property in css/dashboard_css.css which is causing non-WPSOLR pages to render text fields incorrectly:

input[type=text] {
    width: 300px;
}

To replicate the problem, activate the plugin and edit a post whose type has “page attributes” enabled. The “menu order” field will break out of its container.

Please can the CSS be amended to stop affecting non-WPSOLR admin pages?
