Something like this for vimium, or else sites with a sidebar get impossible to navigate`

This is a vimium issue, but it opens source by doing gs in vimium C.

Vimium C has such features:

1. Its LinkHints.activateHover will auto mark an element (or an outer element) scrollable, and then j and k work.
2. Render hint markers for scrollable areas in dark red

• 1. an edge case is, when a scrollable area is also "clickable", its marker won't be dark red, but this should have little impact

So you may fell free to select any common black hint marker and the the scrollable box containing it will be auto-selected by Vimium C and then j and k should work on it.
