How to bookmark every "N" line in Notepad++?

Question

Regular Expressions

Hello!
Guys, please tell me how to bookmark every "N" line in Notepad++. Previously, before version v7.7.1, I used the regular expression " ([^\n]*\n?){100} " (without quotes), for example, every 100 lines are marked here, but for some reason this function does not work in new versions .
Thank you.

(\K[^\n]*\n?){100}
