Automatic update from web-platform-tests [CSS Modules] Fix CHECK when styles are preloaded from the cache When style modules are preloaded from the cache, there's a ScriptForbiddenScope deep in the stack that gets hit. This change fixes the CHECK by allowing user agent scripts for this scenario. A test was added that hits the DCHECK without this fix.
