Unable to verify twitter account with "Tweet privacy/Protect my tweets" is set

While to trying to verify my twitter identity with option "Tweet privacy / Protect my Tweets" is active, keybase couldn't verify the tweeted msg until I unset the setting from: https://twitter.com/settings/security
under "Privacy".

The report identifies Keybase's Twitter verification flow and the Twitter Privacy setting, but names no repository file, test, or entry point. Start by locating the Twitter verification implementation and reproducing the failure with protected tweets; done requires a decided and tested outcome for verification while that setting is active.
