title: HTML autocomplete/snippets stopped working when I changed the file language type to `HTML (EEx)` for a .html.eex file
body: <p>I guess there's some built in snippets because I used to be able to do stuff like type: <code>h2</code> + <code>tab</code> and get <code>&lt;h2&gt;|&lt;/h2&gt;</code>. However my language snippets weren't working, so I switched the file language type to <code>HTML (EEx)</code>, for <code>.html.eex</code> files. Now my language snippets work (from a package), but now I don't get any HTML snippets. Is there a way to tell VSCode to treat <code>.html.eex</code> files as if they were HTML files? I sort of want to merge the <code>HTML</code> and <code>HTML (EEx)</code>  language file types into one. What's the best way to fix this?</p>
