Sample Bindings Example: "Download this example" button downloads an empty project

If we go to https://doc.qt.io/qtforpython-6/examples/example_samplebinding_samplebinding.html and click "Download this example", the downloaded archive (https://doc.qt.io/qtforpython-6/_downloads/587db9be39df54bbbf7faebc5ee6a3fe/doc.zip ) only contains these two files and no source code:

• widgetbinding.md
• widgetbinding.pyproject
