Can't scroll with arrow keys in font selection drop down

In Rhino 5 I create text at said height. Then I go to the properties tab and go to the text button. I select the font drop down and can use my keyboard arrows to scroll through the different installed fonts. Getting a visual indicator for my text so I can decide which font to use. In Rhino WIP 6 after I click the drop down, I then go to use the arrows and it just pans in the viewport instead of scrolling through the font selection.
Has the way you access drop downs changed, or is there a setting I have to check? Is this something that can be changed back to the way Rhino 5 handles it?
