ImageSize in Image widget is not set when setting a texture as a brush

ImageSize in Image widget is not set when setting a texture as a brush

Description

Since FDeprecateSlateVector2D has been implemented in 5.2, the following function calls will always fail. Therefore, the ImageSize is not updated.
This problem does not occur in 5.1.

    void SBrushResourceObjectBox::OnBrushResourceChanged()
    {
...
            // Update the image size to match that of the incoming new texture.
            // TODO: Should we always do this?  Or should we avoid doing it if there's already some 'set value'
            // problem is we don't have a way to track that right now.
            ImageSizeProperty->SetValue(CachedTextureSize);  // This function call fails

The following code works as a work around : 

bool FPropertyHandleVector::Supports( TSharedRef<FPropertyNode> PropertyNode )
{
....
	if( StructProp && StructProp->Struct )
	{
		FName StructName = StructProp->Struct->GetFName();

		bSupported = StructName == NAME_Vector ||
#if 1  // workaround
			StructName == NAME_Vector2f ||
			StructName == FName("DeprecateSlateVector2D") ||
#endif
Steps to Reproduce
  1. Create Widget blueprint
  2. Place Image widget from the Palette window
  3. Select the Image widget and set a texture to Brush property
  4. See ImageSize property in detail pane

Result:

     ImageSize property is not set from the specified texture size

Expected Result:

    Update ImageSize from texture size
