What happened?

Description

When editing and saving a nested element a revision is not created until after you save the parent despite the changes to nested element being applied to the canonical element. This can be observed when using a Matrix field in table view mode (inline mode does not exhibit this behaviour). We also see this issue within Commerce when managing Products/Variants, as well as in our own nested elements.

Steps to reproduce

Requires a Matrix field with oneEntry type and field. The Matrix field should be set to "Display as an element index" and "Display in a table".

1. Create a new Entry and save.
2. A a new Matrix Entry and save, note a revision has been created.
3. Edit the Matrix Entry and save, note a revision hasn't been created. If you were to view the parent Entry on the frontend you will observe that the Matrix Entry edit is published.
4. Save the parent Entry, note a revision has now been created.

At the 1:00 minute mark the changes to the Matrix Entry are "live" so it doesn't appear to be a UI bug with the parent Entry not tracking changes. Craft does know something has changed as it will create the revision with the edits to the Matrix Entry when resaving the parent.

Expected behavior

When performing step 3 a revision is created.

Actual behavior

When performing step 3 a revision isn't created.
