That's what I meant.  In a normal frame the maximize button is enabled.
Hit M-f10 and the maximize button is still enabled.

This happens because M-f10 and hitting the button are unaware of each
other.  M-f10 tries to emulate maximization by making the frame cover
the entire workarea.  Clicking the maximize button does more or less the
same but (1) also drops the outer frame borders and (2) enables the
restore size button.
