Serverside Dynamically loaded CSS module file insertion adds css-files as usual static files with special data-n-p tag, that is used in page transition logic. That files get removed on page transition cause they are not explicitly required in scope of page.
Mini-css-extract-plugin adds style tags at chunk insertion without any tags and leave them be, no matter how many page transitions were made.
I removed data-n-p tag from dynamically loaded css module files and added new data-n-d tag for it.
Fixes#16950
To prevent FOUC, discussed in #10557 i need to store information about css file dependencies for chunk. Right now current implementation just throws away everything but js.
Can there be more than one css file in chunk? If no - code will be simplified.
closes#10557
