Function templateMayMatch

templateMayMatch(content: string, query: TemplateQuery): boolean
Cheap pre-check: can the template possibly contain a hit for query? Avoids parsing templates that do not mention any searched token.
Parameters
- content: string
  Raw template text.
- query: TemplateQuery
  What to look for.
Returns boolean
false only when no searched token occurs in the text; true when the selector cannot be parsed.
