Percent of parent layout

When setting the width of a component, e.g. the width of a button or a layout nested within another layout, if I chose to go with percentage, ai2 calculates the width according to the total width of the screen and not the parent layout.

Can this be fixed?

“Percentage” here means percentage of the screen width or height, not percentage of a containing component.   For a button inside a horizontal arrangement, a width of 50 percent means half the screen width, not half the width of the arrangement.
