here is what this.restore does:

  • get text from mutation.target.data,
  • calculate range by text
  • reset mutation.target.data to empty

so only the first execution of this.restore is effective
the next execution will get empty text from mutation.target.data, and return wrong range, which is the cause of the issue #4046

if (range) context.range = range;
}
}
}
