Annotations control not localised

[kojimaru14]

Environment:

• Preview and/or Annotations version:
  • Content Preview UI Element: v22.2 (loaded from https://cdn01.boxcdn.net/platform/elements/22.0.0/ja-JP/preview.css and https://cdn01.boxcdn.net/platform/elements/22.0.0/ja-JP/preview.js)
  • Annotations: v5.1.0 (as of this post. Dynamically loaded from https://cdn.skypack.dev/box-annotations@latest)

Desktop:

• OS: Windows 10
• Browser: Chrome
• Version: 133.0.6943.142

Steps to reproduce the problem:
This is the codepen used for showcasing this behaviour: https://codepen.io/kojimaru/pen/oNwrLBW
I tried setting locale to Japanese by passing the following option as the parameter for creating BoxAnnotations class, but that didn't help.

var annotationsOptions = {
  features: {},
  intl: {
    locale: "ja-JP",
  }
}

What is the expected behavior? (Screenshots can be helpful here)
"ja-JP" locale should be supported as per https://github.com/box/box-annotations?tab=readme-ov-file#supported-locales

What went wrong? (Screenshots can be helpful here)
Annotations controls (including tooltip) are not localised and are always displayed in English
