# Enable STS 
# Navigate to www.youtube.com
# Use search key + mouse on the side bar on the left. Note that it is read properly because it isn't layered over anything else
# Navigate to any video. I used https://www.youtube.com/watch?v=fiH9edd25Bc
# Expand the side bar on the left
# Use STS to read the contents of the side bar on the left
Expected: just read text in side bar
Actual: reads info underneath first then side bar info
# Use STS to read profile menu on the right
Expected: just read the menu
Actual: reads content underneath first
