            Bug ID: 255439
           Summary: always use document URL as the source of a
                    ResizeObserver loop limit error
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: DOM
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: heycam at apple.com

In Document::updateResizeObservations we throw an error if we exceed some limit for the number of times we loop processing ResizeObserver notifications.  This uses getParserLocation to get the location to use in the error, which returns the empty string if parsing the document has finished.  I think we should just use the document URL.  When we pass in the empty string to reportException, we end up censoring the error message as "Script error." because we think the error came from a different origin, and the "ResizeObserver loop completed with undelivered notifications." message gets lost.
