[#105] Markup after a spacing in an opening tag in your template could not be parsed

[klebba]

My template does string interpretation of an attribute value:

<div id="container">
  <a href="/"><button>Main</button></a>
  <ul>
  ${list.map(item => [item.hash, html`
    <li><a href="/series/${item.hash}">${item.hash}</a></li>
  `])}
  </ul>
</div>

I know this is not allowed anymore, but the error message is a bit confusing:

Yah, to be fast the rules are simple to catch issues as we let the state machine run. HOWEVER, once an error is hit — we typically run more expensive pattern matching to try and provide more precise messaging.

Totally reasonable to try and add specifications to catch this case and do more to message. I think this fits nicely into the “fit and finish” phase of work.
