Is it possible to enable all of the features to the template html string which VSCode provides to an independent html file?

[b4git]

Currently, it appears that many features which are available inside a html file are not enabled for the templated html string. For example:

// in a Test.ts file:
const x = html`<h1>Rename test</h1>`;

If the html content was in a separate html file, VSCode allows to do things like renaming, but trying to rename the <h1> tag above in VSCode says: You cannot rename this element.

What settings should be used to enable such features?

‘Rename symbol’ via the context menu works for me to rename the tags.
