The commit 1d2d25dcadda0764f303183ac091d0c87b432566 (https://github.com/ruby/ruby/commit/1d2d25dcadda0764f303183ac091d0c87b432566) breaks the grapheme_clusters method on a byte slice

``` (commit 1d2d25dcadda0764f303183ac091d0c87b432566) ((HEAD detached at 1d2d25dcad)) $ ./ruby --disable=gems script.rb ["안", "\xEB"] ((HEAD detached at 1d2d25dcad)) $ git checkout HEAD^ (114e71d06280f9c57b9859ee4405ae89a989ddb6) ((HEAD detached at 114e71d062)) $ make -j ...

the expected result here is almost certainly the latter output, and not the former.

to clarify: grapheme_clusters used to ignore partial characters from a byteslice, now it does not. ---------------------------------------- Bug #20305: commit 1d2d25dcadda0764f303183ac091d0c87b432566 breaks grapheme_clusters https://bugs.ruby-lang.org/issues/20305#change-107003 * Author: fablestales (Fable Tales) * Status: Open * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- given a script: ``` #script.rb p "안녕".byteslice(0, 4).grapheme_clusters ``` The commit 1d2d25dcadda0764f303183ac091d0c87b432566 (https://github.com/ruby/ruby/commit/1d2d25dcadda0764f303183ac091d0c87b432566) breaks the grapheme_clusters method on a byte slice ``` (commit 1d2d25dcadda0764f303183ac091d0c87b432566) ((HEAD detached at 1d2d25dcad)) $ ./ruby --disable=gems script.rb ["안", "\xEB"] ((HEAD detached at 1d2d25dcad)) $ git checkout HEAD^ (114e71d06280f9c57b9859ee4405ae89a989ddb6) ((HEAD detached at 114e71d062)) $ make -j ...
