Bug Report
From what I could tell, this is a common pattern with JSDoc used to properly document the type of a loop variable. It does not seem to work in VSCode.

jsdoc for loop type
🕗 Version & Regression Information
- This is the behavior in every version I tried, and I reviewed the FAQ for entries about JSDoc.

💻 Code
for (/** @type {HTMLElement} */ const e of document.body.querySelectorAll('.test')) {
e.style.display = 'none';
}
🙁 Actual behavior
e is typed as Element
🙂 Expected behavior
e should be typed as HTMLElement, as I have overridden it via @type.
As an example, if I were to change the code to this:
/** @type {HTMLElement} */ const e = document.body.querySelectorAll('.test');
VSCode correctly picks up that I'm wishing to override e as an HTMLElement (and complains about missing interface implementations, but, that's not the issue here - in fact that's expected!)
