Tooltips inherit font-family/weight but not size

Created by: gregtyler

If a tooltip is put inside a container with a different font family/size/weight set, the font size is reset but the font and weight aren't. This seems inconsistent, I'd expect the font-family/weight to be reset to @font-family-base and "normal".

Example on bootply: http://www.bootply.com/5CEDW2oLui

Example code:

<div style="padding:40px;font-family:'Comic Sans MS';font-weight:bold;font-size:2em;">
  Tooltip over <span title="test" data-toggle="tooltip" style="color:red">this bit</span> of string.
</div>

$('[data-toggle=tooltip]').tooltip();
