QListWidget setCurrentRow inconsistent with NVDA / Braille Display

QListWidget row changes, when the ListWidget does not have focus result in inconsistent Vocal, Braille and Screen outputs when using NVDA 2019.

A program with a tab widget, and on one tab, have a QListWidget, and on the second tab have a PlainTextEdit.  Using setFocus, select the PlainTextEdit, and everything works fine:

• Screen shows PlainTextEdit
• Voice reads first line
• Braille display shows first line

If, after setFocus of the PlainTextEdit, the QListWidget selected row is changed, even though the QListWidget does not have focus, things are inconsistent:

• Screen shows PlainTextEdit
• Voice reads first line, then the selected row of the QListWidget
• Braille display shows the QListWidget

Repeating the same again does something different, probably because the selected row of the QListWidget doesn't actually change:

• Screen shows PlainTextEdit
• Voice reads first line
• Braille display shows first line

See the attached program.
