I think GCPM floats that cause column intrusions should be specified differently. Otherwise, "float:left|right" should forever behave in multicolumn environment exactly as it does in multipage environment: float to side of page/column and get clipped if it doesn't fit. 

Then if somebody takes existing web content and changes number of columns, and columns are generally wide enough for the content, nothing unexpectedly crazy will happen (such as maybe page header intruding into page footer). 

In GCPM there is already "float:column" which hands scenarios that really target multicol layout. If we need a feature that puts such float in current column that would be a small addition to GCPM syntax.

Also sprach Alex Mogilevsky:

Either way, we will end up with different behavior between those UAs that support the multicol spec, and UAs that support multicol+GCPM. 

For example, I'm sure some authors will start relying on floats being clipped. When GCPM is added to the mix, floats will no longer be clipped. Is that ok, or do we need to add syntax to explicitly state that floats should overflow & intrude?
