<p> Tags Don't Autocomplete

When one types an opening (non-self-closing) HTML tag, the editor auto-completes it with the corresponding closing tag. `

` tags, however, seem to be an exception to this.

Locate the editor's HTML tag-autocomplete entry point and any existing autocomplete tests; start by tracing how non-self-closing tags are classified. Verify that opening p tags receive matching closing tags and that existing autocomplete behavior remains unchanged.
