mouse hover not work between -90 and 0 degree after setPieStartAngle(-90)

I am using SmartClient Version: v10.0p_2015-05-01/EVAL Deployment (expires 2015.06.30_04.46.48) and FireFox ESR 24.3.0.

I want to change the starting position of data label to -90 degree or 270 degree which is north direction from PIE chart.

So, I tested using SimpleChart.java in the EE sample.

I added the following codes in the sample.

chart.setShowValueOnHover(true);
chart.setPieStartAngle(-90);

However, when hovering mouse between -90 and 0 degree, 'showing value on hover' does not work.

Please refer to the attachments.
