Three scenarios tested. For all three scenarios, the expected result is for the content to overflow Region 1 as a multi-column container before flowing into Region 2. All fail, but Scenario 3 fails a little differently: Scenario 1: Region 1: Smaller width & height than Region 2 Test file: regions-multicolumn-024.html Actual Result: What should overflow as a second column flow directly into Region 2 Scenario 2: Region 1: Smaller height than Region 2, auto width Test file: regions-multicolumn-026.html Actual Result: Same as Scenario 1 Scenario 3: Region 1: Smaller width than Region 2, auto height Test file: regions-multicolumn-028.html Actual Result: The content overflows Region 1 correctly as a multi-column container, but does not then flow into Region 2.
