Ah ok, glad to know, thank you.
I had been testing it in Chrome, now I tested it in Firefox (this time in Safe Mode) and in the console get 1 error:
Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”).
and 2 warnings:
This page uses the non standard property “zoom”. Consider using calc() in the relevant property values, or using “transform” along with “transform-origin: 0 0”.
unreachable code after return statement ...build-waiter.js:214
I imagine those aren’t related but I’m not sure.
