@name         Unblock AlgoExpert text selection
@version      20211207.08.05
@namespace    userstyles.world/user/nenad
@description  By default, AlgoExpert does not allow text selection in some places. I find that slightly annoying as I am used to marking text when I'm reading and sometimes I'd like to take notes by copy-pasting.
