<pre>Summary:
SafariForWebKitDevelopment crashes failing to find a symbol:
Starting SafariForWebKitDevelopment with DYLD_FRAMEWORK_PATH set to point to built WebKit in /Users/dcrousso/Documents/Projects/WebKit/WebKitBuild/Release.
dyld: Symbol not found: __ZN9Inspector17BackendDispatcher19reportProtocolErrorEN3WTF8OptionalIlEENS0_15CommonErrorCodeERKNS1_6StringE
Referenced from: /System/Library/PrivateFrameworks/WebInspector.framework/Versions/A/WebInspector
Expected in: /Users/username/Documents/Projects/WebKit/WebKitBuild/Release/JavaScriptCore.framework/Versions/A/JavaScriptCore
in /System/Library/PrivateFrameworks/WebInspector.framework/Versions/A/WebInspector
Notes:
- The exported symbol changed when we switched from WTF::Optional to std::optional
- I think we may need to provide a Legacy WTF::Optional implementation for Legacy Safari support.</pre>
