When the tool menu is minimised each click on a tool causes the menu to expand and then contract

When the tool menu is minimised each click on a tool causes the menu to expand and then contract. This is down to the minimised state being handle by JS and a cookie, rather than the initial server side render cycle. It would be nicer if we could pass a flag to portal/tool indicating that we want the tools rendering minimised to start with and thus avoiding the glitch entirely. Or, we could push the minimised preference into the user's preferences using ajax and then honour that in the portal render.
