Yes we are missing a return here in the Paste routine in MainWindow.cpp:

if (!html.isEmpty()) {
        QMessageBox msgBox(QMessageBox::Question,
          tr("Clipboard contains HTML formatting"),
          tr("Do you want to paste clipboard data as plain text?"),
          QMessageBox::Yes|QMessageBox::No|QMessageBox::Cancel);
        msgBox.setDefaultButton(QMessageBox::Yes);
        // populate the detailed text window - by HTML
        msgBox.setDetailedText(html);
        int rv = msgBox.exec();
        if (rv == QMessageBox::Yes) {
            m_WebView->triggerPageAction(QWebEnginePage::PasteAndMatchStyle);
        } else if (rv == QMessageBox::No) {
            m_WebView->triggerPageAction(QWebEnginePage::Paste);
        } else {
            // they have hit Cancel so paste nothing
            return;
        }
        return;   // fix missing return
    }

I will push that fix to PageEdit master.
