Fixes: #1271

How to manually test:

1. Check out PR
2. yarn start:dev:preview should bring up the preview/demo UI. There should be a Fake Target, with a Demo template. Topology view should work, dashboard should work, recording start/stop/archive/delete should work, expanding recording for automated analysis should work. GraphQL-powered things will not work, snapshot recording creation does not work.
3. yarn run build:preview:notests && cd dist && python3 -m http.server, then open http://localhost:8000 in a browser. The preview should work just the same as in the step above.

Would this patch help? The mock code just needs to get the same wsUrl as in the application code.

I tested with and it seemed OK :D

yarn build:preview:notests
cd dist && npx browser-sync start --server

Nice, that seems to work. I did the same build-and-local-webserver trick, except instead of npx browser-sync I used python3 -m http.server - same idea.

Want to commit that patch to this branch so you get credited for the contribution? :)

Haha nicee, sure :D I don't have access to your fork though so I opened: andrewazores#2

[andrewazores]

Ah right, that would be a maintainer privilege that I can add commits to peoples' PRs like that...
