unchecking "Custom Values" should show description text
Mark and I think that unchecking "Custom Values" in the Security Slider should immediately cause the descriptive text to be displayed for the selected level. Steps to reproduce:
- Open about:config and toggle a security-related pref.(e.g., svg.in-content.enabled).
- Open the Privacy and Security Settings window. Uncheck "Custom Values".
The text is displayed immediately if a new level is chosen via the slider or if "Restore Defaults" is clicked.
