Text in a math field that is removed in Libreoffice

For instance, importing the attached equation a^"*" from microsoft word docx, (written in Libreoffice Formula editor as {a}^{"*"}) removes the quotation marks on import leaving {a}^{*} which returns a broken equation error immediately, because * is an operator.

The quotation marks, or "non math feature" is needed for importing docx equations which happen to also be any of the Libreoffice operations, as is stated in the Libreoffice math guide.

On re-exporting, the quotation marks / non math region is still missing which leads to further errors down the line (e.g. re-importing an asterix breaks the equation immediately as it is treated as an operator)

This is repeatable with quotation marks around anything in a Word docx. But, creating a docx in libreoffice with quotations in an equation works fine.

In summary, it appears as though the non-math text feature of microsoft (which you can access using quotation marks in either software) is ignored by libreoffice, despite libreoffice having the equivalent feature of using quotation marks

The same happens with RTF import, an asterisk within a \mr text run in math is not quoted on import and displays as ¿.

LibreOffice version 6.0.3.2.
