Choice tags are gone after state reloading

[Shepard]

Describe the bug

I have a story with tags on choices. I can find these on the choice objects initially. But when saving the state at a choice to JSON and then later reloading the story state from that JSON (in a fresh Story object), there are no tags on the choice objects anymore.

To Reproduce

import inkjs from "inkjs";

const storyContent = `
Hello, world!
* [Make a choice # just some tag]
- Great choice!
`;

let inkStory = new inkjs.Compiler(storyContent).Compile();
inkStory.ContinueMaximally();
let choices = inkStory.currentChoices;
if (choices.length) {
  console.log("Choice text before save:", choices[0].text);
  console.log("Choice tags before save:", choices[0].tags);
}
const stateJson = inkStory.state.ToJson();

inkStory = new inkjs.Compiler(storyContent).Compile();
inkStory.state.LoadJson(stateJson);
choices = inkStory.currentChoices;
if (choices.length) {
  console.log("Choice text after save:", choices[0].text);
  console.log("Choice tags after save:", choices[0].tags);
}

Output:

Choice text before save: Make a choice
Choice tags before save: [ 'just some tag' ]
Choice text after save: Make a choice
Choice tags after save: null

Expected behavior

The console.log statements before and after state reloading should provide the same output. However choices[0].tags is [ 'just some tag' ] before and null after.

Environment

• OS: Windows
• Node.js version: v16.19.0
• inkjs version: 2.2.1

I extended my example a bit. If I continue the story from the reloaded state, then later choices don't have the same problem. It's only the choice at which I saved the state.

import inkjs from "inkjs";

const storyContent = `
Hello, world!
* [Make a choice # just some tag]
- Great choice!
* [Make another choice # another tag]
- Not bad!
`;

let inkStory = new inkjs.Compiler(storyContent).Compile();
inkStory.ContinueMaximally();
let choices = inkStory.currentChoices;
if (choices.length) {
  console.log("Choice text before save:", choices[0].text);
  console.log("Choice tags before save:", choices[0].tags);
}
const stateJson = inkStory.state.ToJson();

inkStory = new inkjs.Compiler(storyContent).Compile();
inkStory.state.LoadJson(stateJson);
choices = inkStory.currentChoices;
if (choices.length) {
  console.log("Choice text after save:", choices[0].text);
  console.log("Choice tags after save:", choices[0].tags);
}

inkStory.ChooseChoiceIndex(0);
inkStory.ContinueMaximally();
choices = inkStory.currentChoices;
if (choices.length) {
  console.log("Choice text after save:", choices[0].text);
  console.log("Choice tags after save:", choices[0].tags);
}

Output:

Choice text before save: Make a choice
Choice tags before save: [ 'just some tag' ]
Choice text after save: Make a choice
Choice tags after save: null
Choice text after save: Make another choice
Choice tags after save: [ 'another tag' ]
