Test case

<rdar://problem/11135525>

When the contents of a multi-column block includes overflowing blocks, the column count and height calculation does not account for it. As a result, the number and/or height of columns becomes insufficient to contain the overflow (even as overflow columns). See attached test case.

I’ll land updated results

> fast/line-grid/line-grid-into-columns.html

I couldn’t reproduce this failure

> plugins/iframe-shims.html

Seems to be an unrelated crash

Fixed in <http://trac.webkit.org/r121728>.
