I think I have spotted a bug with the Sections stack. I love using keyboard navigation for these types of websites. The up/down keys work fine. But the right/left keys run into a problem.
Specifically I’m looking at:
When I get down to the section on Slides within Sections I run into problems. Using the left only arrow all is fine, but using the right arrow seems to result in “over sliding” by about 80 pixel. And this over sliding gets added to with each right key (80, 160, 240, etc.).
It’s possible it works fine on some machines. I’m using Safari with a 13" MacBook Pro (late 2016).
