    Description

      If you load a TIFF image using an `AnimatedImage` Item in qml then the application memory will continue to grow until an out of memory crash occurs. The same issue does not seem to happen if using an `Image`.

      To replicate just create a default quick project and load a TIFF image from disk, you should see the issue:

      import QtQuick
import QtQuick.Window

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    AnimatedImage {
        anchors.fill: parent
        source: "file:///C:/Users/<username>/Desktop/streaming/test_images/CCITT_1.TIF"
    }
}

      Attached a zip of two test TIFF images that reproduced the problem for me. The larger the image the faster the memory leak grows.
