TBB 3.5 OS X: EFF SSL Observatory 3.45: Check certificates using Tor is grayed out

So got to EFF HTTPS-Everywhere button then > SSL Observatory Prefs:

Check certificates using Tor (for anonymity) is grayed out and not selectable.

Only "Check certificates even if Tor is not available" is selectable.

It would be a good idea to use Tor to send certificates for inspection don't you think ?
