plugin api: about '\0' prefix, resolvId() retrun the prefixed virtual modules Id, but it isn't prefixed in load() hook.

env: vite 6.2.0

About the '\0' prefix. Link

Office example:

export default function myPlugin() {
  const virtualModuleId = 'virtual:my-module'
  const resolvedVirtualModuleId = '\0' + virtualModuleId

  return {
    name: 'my-plugin', // required, will show up in warnings and errors
    resolveId(id) {
      if (id === virtualModuleId) {
        return resolvedVirtualModuleId
      }
    },
    load(id) {
      if (id === resolvedVirtualModuleId) {  // This Line, id isn't has '\0' prefix
        return `export const msg = "from virtual module"`
      }
    },
  }
}

But in my plugin, I found that the behavior is inconsistent with the examples on the '\0' prefix.

Office example: The prefixed virtual module id is returned in resolveId hook. And then, the prefixed virtual module id is used in the load hook ( if (id === resolvedVirtualModuleId) { ...... ).
example: id: 'virtual:my-module', resolved return: '\0virtual:my-module', in load hook id param: '\0virtual:my-module'.

In my plugin development, I found that I return the '\0' prefixed virtual module id in resolveId hook,
but it isn't prefixed in load hook.
example: id: 'virtual:my-module', resolved return: '\0virtual:my-module', in load hook id param: 'virtual:my-module'.

In addition, in configureServer hook, the prefix is the same as in the official website example /@id/__x00__{id}

I suspect that the official website example is misleading, or there may be other reasons.
