This was reported over in the bootstrap queue and just moving this issue over here.

Patch works and prevents issues I was having with Bootstrap used in tandem with Panels.

Looks like there was some work on this done in parallel over in 3045578. The same lines are now committed to 8.x-4.x-dev. Can we close this issue as it's covering the same ground?
