This seems intentional, see 2babbb59b9, but is very intransparent (might require an additional option?)

Hi, thanks for the report. Yes, can confirm. Though this does not happen if "clear and keep transformation" is used

Hm, this seems intentional, see 2babbb59b9

However, I am not surprised this causes confusion (since it is not mentioned in the documentation, it is mentioned in the tooltip though which says "Completely clear the parenting relationship, including involved modifiers if any").

Suggest to either add it to documentation, or add an option like "Clear and Keep modfiers referencing the parent" - which would then not remove the modifiers.
