For the blender shader graph, set texture node alpha to Channel Packed.

This just should make the viewport view match actual results a bit more closely. Currently if a texture has 0 alpha, it'll show up as black when transparency isn't 0 in the combiner instead of showing the actual texture color. Setting the alpha to Channel Packed makes it show its color which makes combiners which use texture alpha for non-standard purposes display correctly.
