Expected Behavior

OBS not to crash

Current Behavior

OBS crashes

Steps to Reproduce

1. Include browser sources
2. Switch to scene including said sources
3. Become as crashed

I'm not sure if the fault is in the browser source itself but if it is then it shouldn't crash OBS.

Tracing this with the streamer reporting to me, they are using some soruces from Stream Elements, and for them Stream Elements is also taking out their browser itself (whenthey go to access the SE editor). (which of course is sandbox'ed so only kills the one tab)

So I suspect that SE is causing a fault and it's taking out OBS along the way

Anything else we should know?

Attached Crash Logs suggesting libcef is the bad guy

The log I'm looking at has a LOT of

16:59:25.755: [obs-browser: 'Sponsored SE'] Error: TypeError: Cannot set properties of undefined (setting 'alotodifferentthings') Possibly unhandled rejection: {} (https://streamelements.com/overlay/scripts/vendor.js:61333)

all in the same ms, which feels like the browsers in an infinity loop till something gives out

Start with the attached crash logs and OBS log URL, then compare the libcef crash context with the browser-source reproduction involving StreamElements sources. Done means identifying a reproducible cause and a confirmed way to prevent the browser source from taking down OBS.
