TOS interferes with joining a Space?

(Bug, Closed -> Can't Repro, Priority: High, Test Status: No automated tests yet , Reported By Bad Link: Thing 3y284oe not found, )
Summary: If I am accepting an invitation, if I get the TOS page, it prevents me from joining successfully.
When Eric responded to his invitation to join this Space, he got presented with the Terms of Service. After responding to those, he was not a member of this Space. He had to respond to the invitation again to get in.

The problem is likely order of events in the page-handling code, but it needs investigation.
For the time being, the simple workaround is to accept the invitation again.
Later: so far, I can't reproduce this, so I'm closing it. Happy to reopen it if we can figure out a recipe.
