Slashed weather trim on window cause internal issue?

[curbed]

Hello,

I recently had someone install tint and they nicked the run channel on the corner of the window on the front driver side. I would like to know if this will cause any problems for me to go and get it replaced. I wouldn't think it'll cause issues since water seeps into the trim anyway so I thought. 

Will water entering here cause an issue? Would I have to replace this run channel, or is it just a cosmetic problem?

If it were my vehicle, I'd tell the installer that you would like it replaced, perhaps by an auto body shop. 
It is both cosmetically irritating and potentially a leak path.
