Raster Image Fill breaks @symbol_color variable for stroke color

[baswein]

What is the bug or the crash?

If you have a Raster Image Fill or an Outline:Raster Line at the bottom of your layer styling stack it makes the @symbol_color variable applied to the stroke in other layers no longer function. See GIF-

It seems that the symbol_color variable comes from the color of the bottom most symbol layer. Because the Raster layer does not have a color it makes the variable invalid and the color falls back to what is in the stroke field.

A gradient fill layer set to color ramp also doesn't have a color but the symbol_color defaults to the color set in the Overarching Symbol Color field. This seems like the correct behavior.

The current work around is easy: Add a Simple fill layer below the Raster Fill layer. This can even have the Enable Symbol Layer unchecked and still work as the symbol_color.

Thanks- QGIS Rocks!

Steps to reproduce the issue

On a ploygon layer add Simple Fill and a Raster Image Fill Layers to your symbol.
In the Simple Fill settings set the data defined override on the stroke to @symbol_color.
Move the raster image fill to the bottom.
Observe that the stroke on the Simple Fill is no longer the symbol color.
