<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.
