Created PR #99 to fix the same. Please let me know if it does not conform to rules.

Thanks - I hadn't noticed till now, but I can reproduce this on Chrome and Safari.

If the window is made very short then our sidebar links get cropped as well. Perhaps this needs to have an automatic vertical scroll bar?

Sure. I can add a simple overflow edit to the CSS and enable that functionality. Should I do it? Or should I wait till this is accepted and then open a new PR?
