Description

You have the following assets:

• "MF_Test" -> Material Function
• "MB_MyMaterial" -> Material (uses "MF_Test", used as base material for:)
• "MI_MyMaterialInstance" -> Material Instance (of "MB_MyMaterial")

When I change something (for illustrative purposes the Color of the color node in "MF_Test") and then save the material function, it won't update either "MB_MyMaterial" or "MI_MyMaterialInstance":

This will "only" happen when "MB_MyMaterial" has not been opened (in the material editor) yet since the editor was opened.

To fix this, I have to open "MB_MyMaterial", move a node to mark the asset as dirty and then save it.

This is a problem, because it basically means that you will have to open and re- save all materials that use a material function when you change something in that material function.
Depending on how intensive you use material functions, this can also become abig problem (I think most people use material functions for basic stuff like f.e. dithering, and if that won't update in all material it's bad).

Steps to reproduce
