Flexlayout

Hi Webix team,

In this snippet -
If I am using flexlayout gravity 0.9 and 0.1 is not adjusting according to the width.

Please tell me what is the problem in code?
Am I doing something wrong?

Gravity works for cells in a normal layout
Gravity will not work for cells of flex-layout itself, as their sizing is defined by flexbox model, not by gravity property.
