Noticing minor issue with enemy's legs stretching when blown away

[o.0-]

I've been using my Vaykor Hek a lot recently and often use Corrosive and Blast. What I am noticing is that enemies keep their feet firm on the ground and then the legs stretch as an enemy is blown away.

It's a comical effect when multiple enemies are getting stretched in such a manner, so I figured that is something unintended.

I'll try to at least get a screen shot to show what I mean, as I do not have a good setup to capture video.
