    Description

      After adding some items to a QTreeWidget and loading a custom stylesheet, the interactive resize of the columns does not work.

      Default Stylesheet:

      Custom stylesheet:

      The first column is not resizing properly.

      The header is setup this way:

      header = self.header()
              header.setStretchLastSection(False)
              header.setSectionResizeMode(0, QtWidgets.QHeaderView.ResizeMode.Interactive)
              header.setSectionResizeMode(1, QtWidgets.QHeaderView.ResizeMode.ResizeToContents)
              header.setSectionResizeMode(2, QtWidgets.QHeaderView.ResizeMode.ResizeToContents)     

      And the resizing is called like this:

      self.resizeColumnToContents(header.logicalIndex(0))

      Attached is a pyside example to reproduce the issue.

      We believe the issue was introduced with this commit:
