Floats overlapping in Opera 9.00 Technology Preview 1

Test setup:
Two DIVs, each given a specific width that would make them fit next to each other.
The first DIV is floated to the left, but the second is not.  This is normally not a problem
but it becomes one when the second DIV contains a table, as is the case in the example below.

The only fix is to float the second DIV as well but that shouldn't be necessary.

This is box #1
This is box #2
