reset button shows for non members in /_space

[cdent]

the interface should not display the reset button at all when the current user is a not a member of the space

but what happens instead is that after the initial redraw of the space as non-member stuff is first displayed and then hidden, we still get the button displayed.

Here's a screen shot of me viewing pmario's /_space
