Comment:

 I tested the PR using the following endpoint: `/wp-
 json/wp/v2/posts?slug[0][1]=2`

 Before patch:
 {{{
 <br />
 <b>Warning</b>:  preg_match() expects parameter 2 to be string, array
 given in <b>/wp-includes/formatting.php</b> on line <b>1596</b><br />
 <br />
 <b>Warning</b>:  strip_tags() expects parameter 1 to be string, array
 given in <b>/wp-includes/formatting.php</b> on line <b>2256</b><br />
 []
 }}}

 After patch:
 {{{
 {"code":"rest_invalid_param","message":"Invalid parameter(s):
 slug","data":{"status":400,"params":{"slug":"slug[0] is not of type
 string."},"details":{"slug":{"code":"rest_invalid_type","message":"slug[0]
 is not of type string.","data":{"param":"slug[0]"}}}}}
 }}}

 Looks like it fixes the issue.
 Self assigning for `commit`.
