JSDoc syntax highlighting/intellisense not working for JSDoc @import #1049

Description

Type: Bug

Type the following into a JavaScript file:

/**
 * @import { JSONRuleDefinition } from "../types.ts";
 * @import { MemberNode } from "@humanwhocodes/momoa";
 * 
 * @typedef {Object} SortOptions
 * @property {boolean} caseSensitive
 * @property {boolean} natural
 * @property {number} minKeys
 * @property {boolean} allowLineSeparatedGroups
 * 
 * @typedef {"sortKeys"} SortKeysMessageIds
 * @typedef {"asc"|"desc"} SortDirection
 * @typedef {[SortDirection, SortOptions]} SortKeysRuleOptions
 * @typedef {JSONRuleDefinition<{ RuleOptions: SortKeysRuleOptions, MessageIds: SortKeysMessageIds }>} SortKeysRuleDefinition
 * @typedef {(a:string,b:string) => boolean} Comparator
 */

Expected: The @import statement to be highlighted similar to @typedef, and also for intellisense to give me suggestions when typing in between the curly braces.

Actual: Everything from the left curly brace to end of line after @import is green (same as any comment), and typing inside the curly braces does not bring up intellisense suggestions.
