When following  focus, windows do not centre


When you set `follow_focus` the `focus_fit_method` does not apply.

My use case is to set the windows to 90% and centred, leaving the adjacent windows visible. Then when I focus to them using the keys or by mouse they move to the centre.

This use case needs a debounce on the focus events or you end up scrolling all the way to either to start or the end of the row.

MR to follow.
