There is a bug with line spacing when QLabel displays rich text.

ui->label->setWordWrap(true);

ui->label->setText("This is a QLabel with an image: 😂This is a QLabel with an image: <img src='qrc:/img/crm.png'> this is test😂");

When QLabel displays rich text, if the window width changes, the line spacing of the text content becomes abnormal.
