Re: [w3ctag/design-reviews] HTML Horizontal Review: Windows, navigation, agents and agent clusters (#502)

https://tc39.es/ecma262/#sec-forward-progress is the fundamental constraint. This affects dedicated workers and shared workers as specified (they have [[CanBlock]] set to true, though in implementations this might only be true for dedicated workers at the moment). Everything else can in theory run on the same thread, though on CPU architectures impacted by Spectre this would be ill-advised. Hope that helps.
