The inverse occurs when you add an element. This is also wrong.

Issue similar to the  bug 692608 .Hence merging this into 692608.
Please feel free to undupe if not similar

Thanks,

The cause is likely the same, though I'd say that  bug 692608  is a subcase of this one. The problem probably isn't anything to do with position:sticky (given this bug doesn't use it), but rather the fact that editing the content of a scrollable div in a number of ways is shifting the scroll positions when it shouldn't.

My latest jsfiddle shows that you can do this in a number of ways, including just increasing the height of content above the current view.

I've just taken a closer look at the examples in  bug 692608  and I can't see how the bugs are even similar, never duplicates. His is describing "position:sticky" elements become unstuck, so they can be scrolled out of view. 

What this bug describes, is chrome actually scrolling content when the content changes and has nothing to do with "position:sticky" elements. How do I undupe this?

Unduped as per comment #5 & 6.

Able to reproduce the issue on Windows 10, Mac 10.12.2 and Ubuntu 14.04 using chrome reported version #56.0.2924.87 and latest canary #58.0.3020.0.

This is the intended behavior of the scroll anchoring feature, which launched in Chrome 56.
