Comment (by SergeyBiryukov):

 Replying to [comment:60 flixos90]:
 >If it had a notable benefit, it may be worth it, but as far as I can
 tell, this is only needed for a single test. That doesn't mean we need to
 completely remove it. How about we define this constant only if it is not
 defined, or alternatively, only when running the WP core tests?

 I think the latter makes sense, that's exactly what was done the last time
 this came up in [49269] / #51594, before being reverted in [49566]. Looks
 like [https://github.com/WordPress/wordpress-develop/pull/3098 PR #3098]
 goes that route too.
