3.3 Beta /Mac: clicking "OK" in color dialog puts mouse in drag-mode, ESC doesn't fix it (recent REGRESSION).
In 3.3 Beta, Mac, click on any element and open the color dialog from the color swatch. Click on a color, and click OK (don't use keyboard, use mouse/trackpad). The mouse pointer is now in "drag" mode, and moving it will drag the palette panel boundary, and ESC doesn't fix it. It is possible by careful clicks to free the mouse, but the palette panel boundary will remain damaged.
This is a new REGRESSION.
