If there is text in About field in one language panel and that is ALL moved to another language panel, then the change history (in this language) of the About field is completely and irrecoverably lost.
If one leaves just one Blanc character into that language panel, then the change history (in that language) remains and is accessible, even comparisons work but focus is automatically moved to the panel where there is text (English default if not localized).
So the system SHOULD FORCE such single Blanc character into the About field (in that language) instead of allowing it to be completely erased, IFF there EVER has been ANY text in the About field (in that language).

An example: one blanc left in Finnish panel of About field:
