window frame.height grows from start to start if autosave name is not empty, OS X 10.9.3

[Sega-Zero]

Updated to the last release and have noticed a terrible bug: if the window has autosave name set, the window's height grows in every launch!
The height becomes wrong after [NSWindow _setFrameFromString:overrideTopLeft:preferActiveDisplay:constrainFullFrame:force:]
then _contentViewFrame returns wrong height

the stack:
