           Summary: Named flow content does not flow through columns
                    applied to a region
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: rhauck at adobe.com


I have several tests that are variations of the same thing - in each test, I have a region that has a multicolumn layout applied to it. The named flow content flows through the region, but not correctly through the columns defined for it. The varied behavior for the attached tests is as follows:

Test: regions-multicol-004 - text content > 1 three-column region, no overflow
Result: The text flows through the region, but is not placed correctly in the columns defined
Expected: The text should be laid out according to the multicol definition with a 30px gap between columns

Test: regions-multicol-005 - monolithic content > 1 three-column region, no overflow
Result: The content flows through the region, but overflows the bottom of the region rather than wrapping to the next columns
Expected: The content should wrap to the next columns. If I remove the regions and simply add the content as a child of the multicol container, the monolithic content wraps into the column layout.

Test: regions-multicol-006 - text content > 1 two-column region > 1 regular (non-multicol) region (Derived from Example 5 in the spec)
Result: The text flows through the region, is not placed correctly in the columns defined, but does flow correctly to the next region in the chain
Expected: The text should be laid out according to the multicol definition with a 30px gap between columns

Test: regions-multicol-007 - monolithic content > 1 two-column region > 1 regular (non-multicol) region - (Variation of Example 5 in the spec)
Result: The text flows through the region, does not wrap to the second column, but does flows into the next region and overflows it
Expected: The content should wrap to the next column before flowing into the next region.

Test: regions-multicol-008 - non-text, fragmentable content > 1 two-column region > 1 regular (non-multicol) region (Variation of Example 5 in the spec)
Result: Same as regions-multicol-007
Expected: Same as regions-multicol-007

Test: regions-multicol-009 - text content > 1 regular (non-multicol) region > 1 two-column region (Variation of Example 5 in the spec)
Result: Text flows through the first region, but does not flow into the second region at all. Instead, it overflows the bottom of the first region
Expected: The text should flow into the next region and through its column layout

Test: regions-multicol-010 - monolithic content > 1 regular (non-multicol) region > 1 two-column region (Variation of Example 5 in the spec)
Result: Same as regions-multicol-009
Expected: Same as regions-multicol-009

Test: regions-multicol-011 - non-text, fragmentable content > 1 regular (non-multicol) region > 1 two-column region (Variation of Example 5 in the spec)
Result: Same as regions-multicol-009
Expected: Same as regions-multicol-009
