QStyledItemDelegate::setEditorData is called unnecessarily after setModelData

In the Qt item delegate system, after setModelData is called to update the model with the editor's value, Qt unexpectedly calls setEditorData again on the editor. This leads to unnecessary synchronization of the editor, even though the model has already been updated and the editor should be hidden or closed.

Expected Behavior: Once setModelData is called and the model is updated, Qt should no longer call setEditorData for that editor, as the editor is either no longer visible or in use. The view should update directly from the model, not from the editor.

Actual Behavior: After setModelData updates the model, Qt calls setEditorData again on the editor widget (e.g., QSpinBox, QLineEdit), which is redundant because the model already holds the updated value, and the editor is no longer visible.

Attention: you can test using the attachment sample and show the log messages in the console for unnecessarily setEditorData calling.

Thanks.
