Don't check the application occlusion state (this is covered by the pages already), and let the page check visually idle. Remove layers of functions.

Feels like this should have parens to indicate associativity.

Why does this loop use "const auto&" while the other uses "auto*"?

Since allContexts() is a vector of WebContext*, and since the range-based for loops do not intend to modify the contents of the vector, I think they should both just say "auto" -- neither "auto*" nor "const auto&".

This should use auto*.
