Before fix:

After fix:

The fix is:

.panel-body:after {
content: " ";
display: table;
}

The CSS for that is still present, it's just been moved: https://github.com/twbs/bootstrap/blob/master/dist/css/bootstrap.css#L5837:L5838.

JS Bin?

[1730wang]

just tried in jsbin, seems not an issue if I use the whole css file //netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css

on my local, i use customize downloaded css from http://getbootstrap.com/customize/
only included Grid system and Panels

Confirmed in bleeding-edge master branch Customizer too.

Including utilities.less fixes the issue.

@mdo So, since :extend()-ing mixins still hasn't been implemented in Less, I think we need to move the .clearfix class out of utilities.less and make it mandatory; otherwise, the :extend()s break, hence this bug. Or else we need to make utilities.less mandatory. Thoughts?

@mdo Ping.

For simplicity and versioning and compatibility, we should require the entire utilities.less file—just like we do with scaffolding and Normalize. Simplifies a lot of the pain here and elsewhere without adding much overhead at all.
