Comment (by tyxla):

 I was able to reproduce this issue, too.

 And @Lex_Robinson, yes, your assumption is correct here - `array_merge()`
 flattens the integer indexes. Replacing that `array_merge()` with
 `array_replace()` will do the job, overriding what's necessary from the
 old query vars, but preserving the query vars with numeric keys.

 Patch coming up shortly.
