When it does happen, like any other mistake, it should be corrected. Just like if someone put secrets into git, it should be explained to them why they shouldn't do that, and an expectation should be set not to do it again. If the individual fails to meet that expectation, disciplinary action should be taken, up to and including termination.
I've in fact had this happen to a developer who took PR comments personally. The rest of the team was very glad to see them terminated. Fifteen minutes per day adds up to a lot, and I'm quite sure it's more for staff whose roles are heavier on communication or those for whom anticipating people's feelings comes less naturally.

My point is that a fear of professional criticism is a fundamental flaw in a professional, one that should be corrected to the benefit of the individual and the organization. A leader who refuses to correct this flaw in their reports is holding back their professional development and failing in their role as mentor. One should experience nothing but sublime gratitude that one's mistakes were found and corrected before they caused any damage.
