Subject Re: RFC: basic side floats
Date Wed, 26 Nov 2014 13:44:55 GMT
As a result of the work on lists and floats we can improve current support
for lists when there is a change in IPD across pages. I have committed a
small change to do that to this branch even though it is not really float
related. An example is attached.
