Synchronization of SVGMarkerElement DOM methods and orient attribute is broken

• Component: SVG
• Status: RESOLVED DUPLICATE

[Nikos Andronikos]

Test: https://jsfiddle.net/dodgeyhack/bgLe93sw/

After using the DOM methods:
* setOrientToAuto
* setorientToAngle

And I think after also reading and writing to/from SVGMarkerElement.orientType and SVGMarkerElement.orientAngle.

Then, calling setAttribute with an invalid value causes that value not to be reflected in the attribute as it should.

Minimal JS test:
markerElement.setOrientToAngle(svgElement.createSVGAngle());
shouldNotThrow("markerElement.setAttribute('orient', 'AUTO')");
shouldBeEqualToString("markerElement.getAttribute('orient')", "AUTO");

Fails because getAttribute('orient') returns '0'.

The call stack shows that SetAttributeInternal is called multiple times, which is likely an error:
--Element::setAttribute----------------
    name=orient / newValue=AUTO-START-REVERSE
    --synchronizeOrientAngle------
    shouldSynchronize = 1
    --Element::setAttributeInternal----------------
    name=orient / newValue=0123456789:;<=>?@ABCDEF... snipped the remaining garbage
    --synchronizeOrientType-------
    ownerType.m_orientType.value = 2
    is angle
    --Element::setAttributeInternal----------------
    name=orient / newValue=AUTO-START-REVERSE
    --parseAttribute-------
    name = orient / value = AUTO-START-REVERSE
    returns 0
    --svgAttributeChanged-------
    attrName = orient
    --synchronizeOrientAngle------
    shouldSynchronize = 1
    --Element::setAttributeInternal----------------
    name=orient / newValue=0123456789:;<=>?@ABCDEF... snipped the remaining garbage
    --synchronizeOrientType-------
    ownerType.m_orientType.value = 2
    is angle
