In terms of getting the Visa brexit will not directly affect the policy for Visas given to non-EU nationals. It wouldn't suprise me if extra work as a result of brexit results in delays but I don't see how it would result in a rejection (of course they may still reject your Visa for other reasons).
My bigger worry would be you have planned to end your trip the day after brexit is supposed to hit. While it is hoped that even in the event of a no-deal an arrangement will be made to allow the planes to keep flying, nothing can be gauranteed with the current politial mess in the UK. If you must travel on those dates I would say your safest option is to book a flight on a carrier that is not based in the EU or UK and that does not involve any layovers in (non-UK) EU countries.

Brexit has nothing to do with standard visitor visas. Whether it happens, or whenever it happens, does not make any difference for a standard visitor visa applicant.
now, with all the stories about how much the borders will tighten towards EU and all the scramble that will fall upon outsiders in general
As long as those future visitors are legally travelling between the two zones, nothing is going to fall upon them.
if you have concrete facts, please feel free to share them.
Even Brexit itself is not a concrete fact as of now. I would try this one on Politics.SE.
