Also, in case you missed my answer to your previous question about compatibility issues, Bootstrap is notorious for being a "moving target" technology and not providing backward compatibility from version to version.
They are, however, aware of the migration challenges this poses and maintain a guide to help with identifying the differences. You can find it at this link: Migrating to v5. Incompatibilities such as those you identify here are tagged in the guide with the word "Breaking" in red.
