When the mode-line format is evaluated, Emacs makes its window the
selected window.  If it didn't, how could it show values for that
window in the mode line?

(frame-selected-window) used to remain bound to the window which the user would consider selected, and only (selected-window) changed. I don't know whether it was a bug, or intentional.

If it was a bug, I suppose I could get the desired results with command hooks.
