[ruby-core:99577] [Ruby master Bug#17119] String#partition and #rpartition return wrong result for Regexp patterns containing /\K/

From: kasumi@...

Issue #17119 has been reported by hanazuki (Kasumi Hanazuki).

----------------------------------------
Bug #17119: String#partition and #rpartition return wrong result for Regexp patterns containing /\K/
https://bugs.ruby-lang.org/issues/17119

* Author: hanazuki (Kasumi Hanazuki)
* Status: Open
* Priority: Normal
* ruby -v: ruby 2.8.0dev (2020-08-13T01:14:20Z master 69b5241c36) [x86_64-linux]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
When the Regexp pattern given to `String#partition` and `String#rpartition` contain a `/\K/` (lookbehind) operator, the methods return strings sliced at incorrect positions.

```ruby
# expected -- partitioned at "c" following "b"
"abcdbce".partition(/b\Kc/)  # => ["ab", "c", "dbce"]
"abcdbce".rpartition(/b\Kc/)  # => ["abcdb", "c", "e"]
```

```ruby
# actual -- results are not partitions
"abcdbce".partition(/b\Kc/)  # => ["a", "c", "cdbce"]
"abcdbce".rpartition(/b\Kc/)  # => ["abcd", "c", "ce"]
```
