Bug Report: Issue with Dc.setFill() Function

It appears that the Dc.setFill() function is not working as expected.
Below is some sample code that draws a toggle switch and demonstrates the issue:

    public function setEnabled( isEnabled as Boolean ) as Void {
        var dc = _bufferedBitmap.getDc();
        dc.clear();

        if( isEnabled ) {
            //dc.setColor( 0xe64a19, Graphics.COLOR_BLACK );
            dc.setFill( 0xe64a19 );
        } else {
            //dc.setColor( Graphics.COLOR_LT_GRAY, Graphics.COLOR_BLACK );
            dc.setFill( Graphics.COLOR_LT_GRAY );
        }
        var radius = dc.getWidth() / 2;
        var lowerYCenter = dc.getHeight() - radius;
        dc.fillCircle( radius, radius, radius );
        dc.fillCircle( radius, lowerYCenter, radius );
        dc.fillRectangle( 0, radius, dc.getWidth(), lowerYCenter - radius );

        //dc.setColor( Graphics.COLOR_GREEN, Graphics.COLOR_BLACK );
        dc.setFill( Graphics.COLOR_GREEN );

        var toggleCenter = isEnabled ? radius : lowerYCenter;
        dc.fillCircle( radius, toggleCenter, radius * 0.8 );
    }

Expected Behavior:
When running the code using setColor(), the result looks correct and as intended.

Observed Behavior:
When using Dc.setFill(), the rendered output does not appear as it should.

• It seems that Dc.fillCircle() is ignoring the fill color set by Dc.setFill().

• Additionally, a call to setFill() after a fillRectangle() call still appears to affect the already drawn rectangle, which should not happen.
