Account registers/unregisters in an infinite loop until another account registers (Faucet claim)

[anachr0n1sm]

After claiming honey from the faucet, the "register" button is replaced with "Registered for next period", but returns after a short time (not consistent, but less than 10 secs). The account registers and unregisters continuously.

Monitored for 10 minutes and it stopped after "Remaining sponsorships" was reduced by one, so I'm assuming that the next registration by someone else stopped the loop.
