(Extended tweet) Reply to retweeter is sent to all followers (.@retweeter)

retweet
extended-tweet

#1

This is the scenario (using Python + Tweepy for api calls):

  1. Post tweet from account 1.
  2. Retweet that tweet from account 2, note id of the reweet
  3. Back to account 1 - update status with a user mention of the retweeter, using the new extended tweet option.

update_status(
status=‘some text’,
in_reply_to_status_id=retweet.id,
auto_populate_reply_metadata=True,
tweet_mode=‘extended’,
)

Expected:
@retweeter_handler some text’
Actual result:
’.@retweeter_handler some text’
When the status is posted, the ‘.’ is prepended to the user mention.
Is this the default/ desired behavior when replying to retweeters? If so, is there any way to ‘force’ the reply to use a simple user mention in this case while sill using the new format?
Thanks, if not for solution, at least for a clarification.

I’m marking it as solved, since this [answer] ((Extended tweet): reply to status mentioning several users replies to all mentioned) seems to apply for this case as well.
