auto_resize, width and height

[readme42]

I have a simple grid inside a container.

visible_cols: 2,
 visible_rows: 1,
col_width: 200,
row_height: 450, 

everything is displayed as expected.

If auto_resize: true is added, the width of each col is calculated correctly respecting the width of the menu. But the height calculation ignores the height of the header - it uses the window height.

A short code inspection shows that

max width is calculated by var maxWidth: number = this._ngEl.nativeElement.getBoundingClientRect().width;

max height is calculated by var maxHeight: number = window.innerHeight - this.marginTop - this.marginBottom;

Is this intended? Why is window.innerHeight used instead of the grid elements height?
