Altho a judge's behavior in court generally doesn't form the basis for recusal, the 11th Circuit has ordered "reassignment" where a judge leans so heavily for a defendant they call their objectivity in the eyes of the public into question
This is persuasive authority that Judge Cannon must step aside if the case falls to her as a permanent assignment. Her court & certainly the 11th won't tolerate damage it would do to their credibility if she failed to voluntarily recuse.
