           Summary: regionlayoutupdate event fires continuously
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
               URL: https://github.com/mike-sierra/webplatform/blob/master
                    /examples/bugEvent.htm
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: letmespellitoutforyou at gmail.com


Copy HTML source into local file and open with Canary or Webkit nightly.
The page displays content that threads through a series of CSS regions,
the size of each thresholded with min-/max-height CSS.
Each time the regionlayoutupdate event fires, 
the page increments a counter that displays at the top.

Expected behavior is for event to fire on the NamedFlow only when:

* the regionOverset of any region in the chain changes between fit/empty/overset values.

* possibly if there are less significant changes to layout, such as shifts in linebreaks within any of the regions 

Actual behavior is either:

* event fires continuously onload

* event fires continuously after resizing page
