NPC speech bubbles bounce around too much

NPC speech bubbles bounce around too much when the NPC is moving around, and it makes them difficult to read. I think the problem is that the speech bubbles appear to be anchored to the NPC's head, bouncing around with any running animations and whatnot, causing the bubble to move around in an erratic pattern on screen.

I would like SE to please change it so that speech bubbles are instead anchored to the NPC's base (offset so the bubble appears above their head) so it doesn't bounce around, such that:
- If an NPC is staying in one location, but has animated motion (I.e. dancing in place), the speech bubble will remain stationary.
- If an NPC is walking or running, the speech bubble will move in a straight line, rather than bouncing around with the walking/running animation.

Thanks.
