[Bug]: XML/Text mode changes XML (only when recognized as well-formed XML)

Author: pchemguyCreated Aug 26, 2026Updated Aug 26, 2026

What did you do?

Created a table with cell values like (copied directly from table cell:

xml

<?xml version="1.0" encoding="UTF-8"?>
<xml xmlns="http://www.wipo.int/classifications/ipc/masterfiles">
  <note type="none">
    <noteParagraph>
      <text>Auxiliary devices attached to machines of a different kind, e.g. harrows attached to ploughs, see relevant groups in <mref endRef="A01B0047000000" ref="A01B0003000000" /> for the machines.</text>
    </noteParagraph>
  </note>
</xml>

What did you expect to see?

In both XML and Text modes the same value above.

What did you see instead?

Copied from value viewer (XML and Text mode alike):

xml

<?xml version='1.0' encoding='UTF-8'?>
<xml xmlns="http://www.wipo.int/classifications/ipc/masterfiles">
    <note xmlns="http://www.wipo.int/classifications/ipc/masterfiles" type="none">
        <noteParagraph xmlns="http://www.wipo.int/classifications/ipc/masterfiles">
            <text xmlns="http://www.wipo.int/classifications/ipc/masterfiles">Auxiliary devices attached to machines of a different kind, e.g. harrows attached to ploughs, see relevant groups in <mref xmlns="http://www.wipo.int/classifications/ipc/masterfiles" ref="A01B0003000000" endRef="A01B0047000000"/> for the machines.</text>
        </noteParagraph>
    </note>
</xml>

This only happens when value is recognized as well-formed XML. If I add a symbol at the beginning in the table cell, the value is no longer recognized as well-formed XML, and all fake "xmlns=..." are gone.
