As in summary.
Steps to Reproduce:
1. Freeze rows and/or columns in a sheet
2. Move/copy the sheet to another/new document (choose menu Sheet - Move or Copy Sheet, or in the contextual menu for the sheet tab)
Freeze is lost.
Freeze remains in place.
User Profile Reset: No
Freeze remains when the sheet is duplicated or moved/copied to the same document.
Freeze is lost when complete rows/columns (same or all) are selected, copied and pasted (Ctrl+C, Ctrl+V) into a new sheet. That could be debatable because the new sheet could already have frozen rows/columns.

First I've confirmed this bug so marking it New.
I also searched for duplicates and found plenty of references to bugs around the Freeze rows/columns command but nobody has pointed this out.
It's interesting - to this day excel has a bug such that opening a second window viewing the same spreadsheet disables freeze rows/columns. But that works for calc!
This is different and I know how annoying this issue is so bug for sure.
One last point for any secondary reviewers or developers - the help page for this command (below) is ok but limited. I could not find any reference to what is supposed to happen to freeze rows/columns when duplicating sheets, copying to new sheets, etc.
