title: vscodce's IntelliSense doesn't work with ":" as prefix of a snippet
body: <p>Created this snippet:</p>
  <pre><code>&quot;data-hook&quot;: {
          &quot;prefix&quot;: &quot;:&quot;,
          &quot;body&quot;: [
            &quot;: '[data-hook=\&quot;\&quot;]'&quot;
          ],
          &quot;description&quot;: &quot;Just a shortcut for a data-hook selector creation&quot;,
        }
  </code></pre>
  <p>and when using colon on a file in the project, vscode won't suggest the snippet.
  Only if I use <kbd>Command</kbd>+<kbd>i</kbd> (macOS) I'll see the snippet suggestion.
  When I use other prefixes the snippet works fine.
  does anyone knows how to solve it?</p>
