Describe the Bug

VSCode supports expandable types on hover since at least version 1.102.3 but the current latest Astro extension (v2.15.4) prevents this feature from working. When hovering a type and the Astro extension is active the expand buttons +/- don't appear

Multiple extensions had a problem with this [1] [2]. Seems to be linked to Volar.js which merged a pull request that fixed this.

What's the expected result?

The type expansion buttons +/- should appear when hovering a TS variable or type.
