Anyone know if this bug is resolved or mitigated in KSP 1.11.1?  I didn't see anything in the release notes but I also don't have a chance to fire up KSP right now.

I think so, at least partially. Going through the patch notes I did see this line:

"Fix trajectory changes during rotation caused by MinRBMass being too high"

Looking at the Physics.cfg shows that they've reduced the partRBMassMin from 0.03 to 0.002. So it seems like the new minimum part mass is 0.002t rather than 0.03t. 

I tried weighing some of the previously affected parts and they do appear to be at the correct weight again. 

However there a few parts listed under 0.002t, namely cubic octagonal struts, navigation light mk1s, lightstrip mk1s, and some flag parts. I was guessing they'd still affected since they're under the new minimum.

I'm currently trying to test these parts together with robotic parts and I feel like I'm still running into some mass oddities.

Edit: Updated the main topic with more info
