When you launch Administration Services UI in Internet Explorer, and change the font size of the browser, the new font size is not reflected in Administration Services UI.
When you launch Administration Services UI in any browser, the Administration Services UI collects the browser configurations like font size, font style, and uses these configurations to render the UI elements. On Internet Explorer, these values are not used correctly to render the UI elements.
