<script> elements have a ton of state, but for this particular issue, the 
state that is needed is:

 - presence or absence of src="" attribute
 - "parser-inserted" flag
 - whether the parser in question was an XML parser or HTML parser
 - parser's script nesting level while "prepare the script" is running
 - whether the parser's Document has a "style sheet that is blocking scripts"

Relative to before this edit, the only addition is the check of the 
parser's "script nesting level"; you already had to have all the script 
element state (in particular, you already had to keep track of which 
parser created the element); the parser's "script nesting level", and the 
element's "pending parsing-blocking script" mechanism and the "ready to be 
parser-executed" flag, are not new.
