[GNC] (Multicolumn) Reports no longer sort accounts by account code after date change

[maris_418 at icloud.com]

I’m encountering the same behaviour as Paul, and I can confirm this remains present in GnuCash version 5.10. 

The issue is identical and can be replicated by creating a new book, adding some accounts, then adding some account codes (that differ from alphabetical order). 

Opening a multicolumn balance sheet or profit and loss will show the correct account code sort order on first open. However the report will then revert to alphabetical sorting immediately after changing any date options. It will then remain sorted alphabetically and it does not appear possible to revert to sort by account code. 

I’ve searched bugs.gnucash.org and can't seem to locate a bug report for this - has one been submitted? Thanks.
