HTML attributes are overwritten when editing text

This issue is affecting the Norwix professional services project. Norwix does not want links to be underlined in their application.

When using TextEdit in QML with textFormat set to Text.RichText, and the text is set to contain an HTML anchor with underline turned off

text: "<a style=\"text-decoration:none;\">A LINK</a>

TextEdit will change the  text to something like

<a><span style="color:#0000ff;">A LINK</span></a>

and remove the text-decoration attribute completely.

Attached is an example project. When running the example, change some of the text in the top TextEdit and see the same text appear in the bottom TextEdit, but with the link underlined. The Application Output also prints out the values of TextEdit.text, showing BOTH text as modified.
