What happens if you have a 'initialized' non library entry loaded with full data but while browsing source returns a not 'initialized' data 🤔

What happens if you have a 'initialized' non library entry loaded with full data but while browsing source returns a not 'initialized' data 🤔

'initialized' is being used to make app check for manga's detail. If a 'initialized' non-library entry loaded with full data while source returns a not 'initialized' will make app auto refresh tags/descriptions/author... again when user decides to open the entry. Pretty mush like pull-refresh every time he open that entry (except for not checking chapters).

I think this will be useful too, since a non-library entry can also updates its details information.
Or we can skip overwriting 'initialized' to avoid that.

If the browse manga is initialized update everything otherwise only update the title and thumbnail

although I made the change as per your request but I don't really get it though. When browsing, an non-initialized manga would also only has title & cover available, the rest are null. And null value won't overwrite already existed data of database's entries.
