Any idea why I get no follow up on this jupyter issue? I’m dumbfounded that after I broke it down to having an easy to reproduce minimal notebook and confirmed with the generic third party install, I bisected to find that the problem started with exactly python 3.6.0, spent hours trying to bisect on components and custom config to rule them all out and not a peep from the jupyter notebook devs 
Does this problem not bother you at all?
If it does please vote on the issue, perhaps then it’d get some attention.
Or perhaps you’re not using the TOC extension and the magic follow the execution focus, and jump to currently executing cell shortcut - you’re missing out on being a way more efficient than manually scrolling around at times very long notebooks. Except all 3 are problematic when this bug gets triggered. TOC is still useful despite the bug, but the other two can’t work with the bug.
Clearly it’s been around for at least 2 years now (3.6.0 release). And the bug manifestation seems to be dependent on what each cell contains. The reproducible notebooks always does manifest the bug. It should be easy to verify.
