This was discussed at FTF and resolved as follows:
1) Column balancing does apply in multicol boxes with specified height (see http://www.w3.org/Style/CSS/Tracker/issues/129).
2) Overflow from such boxes behaves the same way with or without balancing – columns are added in direction of line flow (balancing is not applicable with overflow)
3) For in overflow, the ‘column-span’ property has no effect.
Noted special case:
If an element with “column-span:all” does not fit into multicol box, it is pushed to overflow and its ‘column-span’ property no longer has effect. There is a possibility that without “column-span:all” it would have fit within the last column of the multicol box, but that possibility is not evaluated. The element remains in overflow uncioniditionally.
Hakon – could you please verify that my summary matches what we have agreed on?
Thanks
Alex

Subject: RE: [css3-multicol] column balancing and fixed height (RE: Question on Flexbox balance implementation)
Great, it seems we are in agreement on column balancing with specified height.
A related issue is the behavior of column-span in overflow, with specified height.
If in the following markup some column-span elements appear in overflow, it is to be defined how many columns they span:
<div style=“columns:3; height:250px;”>
<p>AAAAAA...</p>
<H2 style=“span: all;”>BBBBBB…</H2>
<p>CCCCCC...</p>
<H2 style=“span: all;”>EEEEEEE…</H2>
<p>FFFFFF...</p>
<H2 style=“span: all;”>HHHHHH…</H2>
<p>IIIIIII...</p>
</div>
We think this rendering would be the most logical:

Would you agree?
