Right click menu appears automatically and does not close in charts-panel
Latest versions of chrome have disabled the "hidden" feature of polymer, and now the right click menu always appears when the panel is opened. Right solution would be to work on TS to use CSS instead of HTML, but due to technical problems I can not build TS elements anymore, a quick workaround is to delete the menu from the swatch cell, as the feature provided by it are anyway also provided by the panel.
