User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0 Build ID: 20150122214805 Steps to reproduce: The problem is with nesting a table inside a table cell which has a `float-left` `div` next to it. See it here in this JSBin : http://jsbin.com/bewane/2/ I saw this bug on a site http://cbseacademic.in/ . Then I have created a scaled down webpage containing only the bug and the expected output. Actual results: The table overflows out of the table cell it is inside. Expected results: The table *should not* overflow out of the table cell it is inside. The same does not happen when the thing is not a table but just a text node. The expected output is same in both IE and webkit (chrome) and that is what I think the output shall be.

This looks like a duplicate of bug 478834, no?
