Alignment of headings wrong when scrolling

I have this problem with content containing images using lazy loading, has anyone found a solution to this problem?

We just released the ToC NG → module which is a fork of this module (ToC.js).

This module was developed as a proof-of-concept for our own needs. We decided to share it with the community.

We rewrote most of the Javascript code and the heading positions are recalculated on scroll, it should probably fix your problem.

Feel free to test it and tell us how it goes.

It has probably been fixed in the new 3.0.x-dev version.

And this depends a lot of the front theme used (sticky navigation bar, etc. etc.) I guess.
