SoFr graphic effect not appearing when used with SoW

[willng3]

I'm not particularly sure whether to consider this a graphical error or yet another "Easter egg" involving SoW.

Here's the situation:  You have an Animated Morning Glory on the field with 4 SoFr as well (therefore the chance of SoFr activating is 100%).  You then play SoW on the Morning Glory.  When the Morning Glory attacks, the 50% damage bonus applies and the Lightning graphic appears, but there's no sign of the SoFr effect taking place.

And before anyone tries to tell me Immaterial creatures aren't affected by SoW...

Spoiler for Lies:

Also, a screenshot of this in action (though it's hard to represent the situation since multiple things should be occurring at the same time...):

Spoiler for Hidden:

To add to the weirdness, if the sound is turned on you can hear SoFr's ability being activated while the Morning Glory attacks before SoW's audio effect drowns it out, but there's still no sign of SoFr's visual effect.

Like I said, it appears to be a slight graphical bug and not much else, but I've found it very confusing as to what's going on in the middle of the duel without that effect appearing, especially when there are not 4 or more SoFr on the field.

Confirmed, I can hear the original "whoo..." (similar to Flying Weapon) from the start of the SoFre animation but you don't get to see the animation nor hear the landing "...oop" (similar to Shockwave). It could be like with Sanctuary and Supernova, two similar graphical (and in this case also audio) effects overriding eachother (instead of smoothly happening alongside eachother).
