1. 8.0 vendor/masterminds/html5/src/HTML5/Parser/Tokenizer.php \Masterminds\HTML5\Parser\Tokenizer::processingInstruction()

Handle a processing instruction.

XML processing instructions are supposed to be ignored in HTML5, treated as "bogus comments". However, since we're not a user agent, we allow them. We consume until ?> and then issue a EventListener::processingInstruction() event.
