Posts block - Load More/Pagination issue when duplicating Posts block

[andeng1106]

Describe the bug

• Related to this link
• Issue both happens if I duplicated the Posts block
• Two issues:
  • Scenario 1: Load More - Loading wrong data. I tried changing query to a custom type (e.g. Books) but it’s still showing Posts data
    • Sample page: https://gambitsandbox.instawp.xyz/andrea/posts-block-load-more-pagination-issue/
  • Scenario 2: Load More & Pagination - When changing pagination in the other Posts block in the same page with the Load More, the Posts block with the Load More is also affected
