Scrollbars / Infowindow height

I’m having an issue with infowindows and I can’t seem to find a good solution for it. In *some* browsers, the info window is showing scrollbars, even though I have minimal information in that window (location name and link – nothing more). I set a generous width for the window (300px). When I display more information in the box, it gets taller, but it’s still always just a bit too short to display everything, and the scrollbars show. Is there any way to resize the height of the infowindow and/or get rid of the scrollbars?

My temporary solution is:
.gm-style div div div div div div { overflow:hidden }

It only works because the current text fits in the box. This is a garbage workaround, and I would love a better solution!
