[visual] calculate preamble position in the main tree iterator (#13964)

Browse source 
* [cm6] use preambleCheckLimit for finding preamble

* extend in case of title or author

* stop at SectioningCommand, include affiliation

* consistent comment

* using 30000 as node index

* use preambleNodes arr

* calc preamble without array

* remove preamble.to check
