Steps to reproduce:

• navigate to: https://codepen.io/cordelia/pen/JwebzJ
• Toggle on browse mode
• m - Move to the frame containing the output
• Tab - focus the button inside the frame
• l - navigate by listbox. Press this a second time to navigate to the veggies list.
• Enter - Toggle off browse mode to allow arrow navigation of the listbox
• arrow up/down - navigate the list

Actual behavior:

Enter is not toggling off browse mode. Manually turning it off does not work either, as focus is not inside the listbox

Expected behavior:

Enter should toggle off browse mode, and allow arrows to move focus up and down the list.
