Current Behavior
New Behavior
(Error disappeared from tagged template literal, and new error for octal escape sequence in untagged template literal)
Implementation Detail
With this PR, invalid escape sequences do not emit errors when they are first scanned. Untagged template literals with invalid escape sequence in it are re-scanned to emit syntax errors.
