Stop label from being long for joined subreddits

Browsing with a long joined subreddit list will cause the label to look a bit weird.

Example: https://libredd.it/r/Android+AnimalsBeingBros+AnimalsBeingDerps+AnimalsBeingJerks+AppleWatch+CatSlaps+CatSmiles+CatsBeingAdorable+FreeTube+Games+Ijustwatched+IllegallySmol+IllegallySmolCats+IpodClassic+LearnRubyonRails+Megadrive+MovieDetails+Music+NetflixBestOf+NintendoSwitch+Possums+Teefers+UKPersonalFinance+airplaneears+apple+aww+brushybrushy+cats+catswhotrill+curledfeetsies+cyberpunkgame+dataisbeautiful+dechonkers+digital_ocean+dogs+dogsareliquid+dogswithjobs+emulation+greebles+happycowgifs+hardware+iOSDevelopment+iOSProgramming+iosdev+kittykankles+learnruby+likeus+mac+mashups+microsoft+movies+netflix+netsec+pihole+playstation+programming+rarepuppers+raspberry_pi+redditsync+rubyonrails+satelliteears+shittymoviedetails+spookyteefies+technology+teefies+vampirecats+velvethippos

That will cause the label to be excessively long
