QLineEdit::editingFinished() not emitted when pressing the clear button and moving focus away

When pressing the clear button inside a QLineEdit and next give focus to another widget, I expect to receive the QLineEdit::editingFinished() signal. This is not the case any more since submit https://codereview.qt-project.org/c/qt/qtbase/+/246539 which was done to fix QTBUG-40.

In attachment I added a minimal Qt Creator project to reproduce the issue:

• Open the project
• Type something in the left QLineEdit
• Give focus to the right QLineEdit

=> "Editing finished." is printed to std::cout

• Click the clear button in the first QLineEdit and give focus again to the right QLineEdit

=> nothing is printed to std::cout

If you try the same thing with an earlier version (I tried 5.12.6) the signal is emitted (and you see "Editing finished." a second time).
