(~<expr>)* results in duplicate meta scopes

[AmjadHD]

main = (~string)*;

string{meta.string string.quoted.double} =
  '"'{punctuation.definition.string.begin}
    (~`\t`{constant.character.escape})*
    ~'"'{punctuation.definition.string.end};

    - match: '"'
      scope: meta.string.xmpl string.quoted.double.xmpl punctuation.definition.string.end.xmpl
      pop: true

since - match: '\\t' doesn't pop the context its scope should not include the meta scope.
