How to prevent shower water from leaking from the side of glass shower door

Shower water often leaks from the side gap of my glass shower door (see attached). I already replaced the old undersweep with new one that seals it better from the bottom, but it seems shower splash still comes out of the hinge gap on the side, which can seep under the flooring and show up as a water spot on the ceiling downstairs in the living room. I would highly appreciate effective ways to block the shower splash from exiting the shower room. It’s really poor shower room design IMO, as I never had such problem in my previous residences, but I don’t have the energy to replace it completely. Thanks!
