Can't change ExponentialHeightFog's inscattering color in a sequencer?

Hey everyone!
Would be very thankful if anyone can help me with this problem:

Basically, I wan’t to change the “Fog inscattering color” in a ExponentialHeightFogComponent within a level sequencer. I am able to change the default inscattering color in the details panel. But when I add the component to a sequencer, and then try to change the color within the sequencer, nothing happens. Other variables can be changed in the sequencer (such as fog density, opacity etc.) but for some reason the inscattering color is not affected…

No matter what value I set in the sequencer (see pic below), the fog is always rendered with its default inscattering color.

It seems to work for me, if I change the density also

It seems like no custom accessor is added in the MovieSceneTracksCustomAccessors.cpp for the “Fog inscattering color”. Therefore, the render state isn’t marked dirty when the color is changed. However, since the density member has a custom accessor added, that is probably why it works if you change the density as well because then the render state becomes dirty.
