Incorrect MissingERBEndTagError

```erb
<span
  <% if @replaceable %>data-menu-button<% end %>
  class="css-truncate css-truncate-target"
></span>
```

Returns:

```
  1. MissingERBEndTagError at 2:2
     `<% if %>` started here but never closed with an end tag. The end tag may be in a different scope.
```

(Using v0.8.0)

I believe this is valid ERB/HTML.
