Fixes #3705 Fixes #4656 - No longer automatically dedupe certain tags. Only the ones we know are *never* going to be duplicate like charSet, title etc. - Fix `key=""` behavior, making sure that if a unique key is provided tags are deduped based on that. For example: ```jsx <meta property='fb:pages' content='one'> <meta property='fb:pages' content='two'> ``` Would currently cause ```jsx <meta property='fb:pages' content='two'> ``` ### After this change: ```jsx <meta property='fb:pages' content='one'> <meta property='fb:pages' content='two'> ``` Then if you use next/head multiple times / want to be able to override: ```jsx <meta property='fb:pages' content='one' key="not-unique-key"> <meta property='fb:pages' content='two' key="not-unique-key"> ``` Would cause: ```jsx <meta property='fb:pages' content='two'> ``` As `key` gets deduped correctly after this PR, similar to how React itself works. |
