Using templates to create page metadata, links are lost when using ref and embed

The page uses templates to generate page metadata. When using the copy block ref and copy block embed operations on the page metadata, the block ID is not added to the MD file, but it can be seen in the database using the show block data command. Specifically, when a new page A is created using a template to create page metadata, including properties such as alias, and then the block ref of this page is copied and placed in another page B, the ref effect can be displayed in real-time. However, the block ID is not written to the MD file of page A. After restarting, the ref in block B becomes an invalid ref, and the re-index operation is also invalid.
