The output of flushDeprecations() no longer formats in a way that can be copied and pasted into the config file. We now get the raw string, which indicates this is likely a behavior change in Chrome DevTools/console.
Example:
"self.deprecationWorkflow = self.deprecationWorkflow || {};\nself.deprecationWorkflow.config = {\n workflow: [\n { handler: \"silence\", matchId: \"this-property-fallback\" },\n { handler: \"silence\", matchId: \"manager-capabilities.modifiers-3-13\" }\n ]\n};"
