Calling XYChart.setPadding prevents chart's legend from resizing correctly.

We observe this issue with SceneBuilder, if we drop an XY chart and set its padding, then resize it, its legend does not resize correctly.

Attached is a small standalone program that shows the problem.

Unzip, build, and run.
Click on "Drop" => a chart is added to the scenegraph
Click on "Padding" => the chart padding is changed to (0, 5, 5, 5)
Click on "Resize" => the chart pref size is divided by 2 and its location is changed - but the legend bar at the bottom keeps its old size.
