I'm planning to use the editor in an environment where the web app comes from a local network and the internet is not always reliable or available. I need a way to react to failed initialization (CDN loading) of the editor. Are there any hooks or mechanisms I can use to implement this right now? Currently I only get a logged error https://github.com/imguolao/monaco-vue/blob/37aca64a5cce3480960cfd0b8b7fe75e03c9f47a/packages/editor/src/hooks/useMonaco.ts#L10-L22 but haven't found a way to react to it properly.
I'm planning to fall back to a simple textarea. Maybe this fallback mode could also be a built-in feature of this plugin?
