Comment (by zwqdpkb086):

 The current wp_staticize_emoji function attempts to optimize by using
 strpos() to pre-check if emojis exist in the text. However, this creates
 significant overhead because it iterates through all 3575 emoji entities,
 performing a costly operation for each one.

 **Issue:** Pre-checking with strpos() is slower than processing all emojis
 directly, as it unnecessarily adds computational complexity.

 **Solution:** Skip the strpos() checks and process all emojis at once.
 This approach consistently improves performance (up to 10x faster) by
 eliminating redundant operations.

 **Recommendation:** Simplify the function by directly handling all emoji
 entities without pre-checks, which results in faster execution without
 affecting functionality.
