Shouldn't English posts be on ruby-core instead of ruby-dev?

[ruby-core:84573] [Ruby trunk Bug#14263] Array Intersection does not seem to use hash

Issue #14263 has been reported by gkellogg (Gregg Kellogg).
----------------------------------------
Bug #14263: Array Intersection does not seem to use hash
https://bugs.ruby-lang.org/issues/14263
* Author: gkellogg (Gregg Kellogg)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: 2.5.0
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
According to the documentation for Array#&, comparison is done using hash and eql? However, this does not seem to be the case in 2.5.0.
If two instances are .eql? but their hashes are not, an array & should be empty:
~~~ ruby
([Var.new('a')] & [Var.new('b')]).empty?
~~~
This test works in 2.4.2 (and all earlier versions), but fails in 2.5.0. See attached script.
