Despite all of the weird and hacky things we have to pass node graph evaluations to another 'thread' both browsers I have tested (firefox-dev and msedge) appear to evaluated the node graph on the main thread. This was confirmed both by running an expensive node and using the profiler.
This is sort of tracked by #1113 although that issue is probably due for an updated description. The latest comments in the thread are more relevant to what's required to finish that implementation.
