In Service Portal, if you have multiple choice variables without a default value set and if you use the tab key to goto the variable, it will not get selected/highlighted.

1. In Orlando instance, create a new catalog item with 2 variables
   
   Variable 1:
   Type: Single line text
   Order: 100
   
   Variable 2:
   Type: Multiple Choice
   Order: 200
   
   Under "Type Specifications"
   Choose direction: Down
   Do not select the first choice: checked
   
   Under Question Choices, create 2 or 3 questions
   
   2. Click on "Try It" then click into the text field and press the Tab key on keyboard and noticed the first radio button is selected
   3. Now go to Service Portal then press the Tab key on keyboard after clicking into the text field and noticed the paper clip icon is selected
   4. Repeat steps 1 - 4 in a New York instance and noticed the first radio button in multiple choice group gets selected and highlighted after pressing the Tab key in Service Portal
