Dialog Card Heading, Text and Answer Dropdown Menus Issue
I noticed an issue with the drop-down menus when selecting the format type in the Heading, Text, and Answer content areas. I tested it out on a Mac (High Sierra) using Chrome and Firefox, as well as on a Windows 7 using Chrome. The same issue occurred with all three platforms.
When attempting to select the dropdown menu to change the format from "Paragraph" to anything else the menu flashes and nothing is selectable.
