Extra horizontal scroll bars in Chrome dev, feature request

[marksz]

I've noticed now for about a month that I'm getting a horizontal scroll bar in pretty much all text boxes like on the main google search page, or even the login and password boxes for github when using this extension or similar ones like Win7 Scrollbars. Please add an option to only customize the vertical but not horizontal scroll bars. If someone more familiar with CSS could tell me the custom CSS necessary to to do this, I'd be most appreciative. Does the example CSS provided include the options selected by the dialogues, or is it only a template for adding options?

I'm on the dev channel on my Chromebook, which is currently running
Google Chrome 64.0.3270.0 (Official Build) dev (64-bit)

I see the example CSS in the "Use Custom CSS (Advanced Users Only)" section of the Rescroller form is not functional. A feature request I'd like to see would be to display the CSS generated by the form selections in the modify text box at the bottom, so those like myself unfamiliar with CSS details, could just change one thing with out having to look up the code for everything else!
