Rendering of textInput.typeahead font and text bar

[lawnboy34]

I've noticed that when I type into the typeahead text bar, the font is partially occluded by the text box (when running in the browser) or appears below the border for the text box (when running in Rstudio).

I've attached screenshots of both. Is there a parameter I can use to make the text box larger or the font smaller so that it's fully visible in the selection box? Otherwise this is a terrific feature!
