What is the latest version of MuseScore Studio where this issue is present?

master commit b86e642

Regression

Yes, this used to work in a previous version of MuseScore 4.x

Operating system

macOS Sonoma 14.6.1

Additional context

Issue reported in https://musescore.org/en/node/368990. This is a MuseScore 4.4 regression, file Untitled_score_xml_Cubase.xml is handled correctly by MuseScore 3.6.2 and 4.3.

Root cause is that the "alter = m_e.readText().toInt();" in MusicXMLParserPass2::harmony() fails (silently). This is apparently cause by extra whitespace in the root-alter element. Notice the difference between both xml files in the zip.

So it is the dufference between the non-working

      <harmony print-frame="no">
        <root>
          <root-step>B</root-step>
          <root-alter>-1
          </root-alter>
          </root>
        <kind text="m">minor</kind>
        </harmony>

and the working

      <harmony print-frame="no">
        <root>
          <root-step>B</root-step>
          <root-alter>-1</root-alter>
          </root>
        <kind text="m">minor</kind>
        </harmony>
