I think no need to relay back because a keymap click in a "header-line"
window will call a function that updates `header-line-format' whose new
content will be displayed in this window anyway.

This means we need extra buffer per every header-line.

I don't understand how do you intend to ensure that the tabbar
of the selected window doesn't disappear if the user types
`C-x 1' (`delete-other-windows')?
