MeasureOverride return Size(0,0) when using as child of container without setting Width and Height

[cuiliang]

Hi, when using control as child of other control and without set Width and Height (wich means sizetype of ContentToSizeNoStretch), the image will not show.

Here is a debug session:

measureoverride.mp4

Size(0,0) is not Empty.

public bool IsEmpty => this._width < 0.0;
