            Bug ID: 170727
           Summary: REGRESSION(r215211): [GTK] Lots of image related tests
                    are timign out, causing the test bot to exit early
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
          Assignee: webkit-unassigned at lists.webkit.org

r215211 changed ImageDecoder::isSizeAvailable() to call encodedDataStatus() in the subclasses, which forces a partial decoding of the image to get the size from the file. But ImageDecoder::isSizeAvailable() is also being called inside the decoders in some places. One of this places is the setSize() method inside each decoder. So a call to isSizeAvailable() when the image size is not known causes the image to be partially decoded to get the size, but as a result setSize() gets called, which calls isSizeAvailable() again, which triggers a new decoder because the size has not been set, and we have another infinte loop.
