I'm having an intermittent problem in Chrome DevTools.
I can set a breakpoint and it sometimes it will, and sometimes it won't work.
I know it's the right file, because when I go back to my IDE and hit save, the page will reload, and the breakpoint will get hit.
It feels like some kind of caching issue; I will have to resave the file I am setting the breakpoint in for it to be caught.
I don't think I'm doing anything special, in this case, it's just a TypeScript model that is consumed by a component tree.
I've had various situations when it wasn't working; I'll update this ticket as I discover them.
