Question Marks inside ERB in Script Tags #230

Description

In Github (HTML+ERB) and Atom I notice this syntax bug when using HTML (ERB - Ruby) or HTML (Rails) highlighting:

<script type="text/javascript">
  variable = <%= Object.test? %>;
</script>

Expected behavior: The closing script tag should be highlighted.
Actual behavior: The closing script tag is not highlighted
Reproduces how often: 100%

My guess would be that the grammar believes this to be the start of a ternary statement. The following has correct highlighting but invalid syntax:

<script type="text/javascript">
  variable = <%= Object.test? true : false %>;
</script>
