Area plots - VertexData missing

[harshpurwar]

Running this:

x = 5:8;
y = [1 2 4 3];
area(x,y); fig2plotly();

results in the following:
Index in position 1 exceeds array bounds.
We had trouble parsing the area object.
This trace might not render properly.

However, if an area plot is done and then if fig2plotly(); is called in a separate statement, it works without any issues.
BTW, area(x,y); pause(1); fig2plotly(); also works.

More specifically, I think the issue is in updateArea.m where the following breaks:

%-get "children" using new HG2 approach-%
area_child = get(area_data.java.firstDown); 
...
xdata = area_child.VertexData(1,:);
ydata = area_child.VertexData(2,:);

area_child.VertexData is empty if fig2plotly() is called immediately after area(). Give it some time and then it just works!
