Windowless browsers don't have Fission enabled. Can we promote windowless browsers to Fission by default? Do we need to add a LoadInfo API to optionally enable Fission in windowless browsers?
The background thumbnailer runs in a windowless browser. It would be nice if it ran in a Fission process, but it is not a security risk (because the background thumbnailer doesn't execute JavaScript from web content). Tracking for Fission Future because this work doesn't need to block shipping Fission MVP.

Actually, the background page thumbnailer does currently run script for the pages it loads. Some specific things are disabled such as media, plugins and popup prompts.
So either this should be reprioritized or, we could disable script if that is actually the intended behaviour.
I'll change this back to fission milestone? for now.
