`org-hidden-keywords' was introduced in Org 9.5 and allows hiding keywords like "#+title:" at the beginning of the buffer. However if you have something like
#+title: A nice title " A nice title" is displayed at the beginning. AFAIK it's common to have a space after "#+title: " in Org files (at least I do it in all my files). It'd be nice to have an option to remove display of this space for keywords included in `org-hidden-keywords'. (Correct me if there's a way to do this already.)
