unexpected serif font due to Glyphicon

Created by: npoppeli

The use of glyph icons and the related CSS styles results in the unexpected appearance of serif fonts. An example can be found here: http://jsbin.com/dequv/1/watch?html,output.

In this example (which passed the W3C validator service), the header and the alert boxes are in sans-serif, but the buttons are in serif, while this is not explicitly indicated. Only code, kbd, pre and samp should use a serif font, according to bootstrap-min.css.
