[BUG] set-option local gets lost for eval -try-client

[losnappas]

Version of Kakoune

9c458c5

Reproducer

decl int testing 0
def -override tex %{ 
  set local testing 33
  eval -try-client tools %{
    echo -debug "val: %opt(testing)"
  }
}

:tex<ret> # => 33
:new rename-client tools<ret>
# => switch back to prev client
:tex<ret> # => 0
# If I run it in the tools client, I get 33.

Outcome

The local option value doesn't carry over to -try-client client.

Expectations

I was expecting local to carry over to the other eval.
