Building on macOS host, macOS target in current master (ee1c9f516a) results in Invalid expression term ')'

Errors so far:

Library/PackageCache/net.gree.unity-webview@ee1c9f516a/Assets/Plugins/WebViewObject.cs(366,16): error CS1525: Invalid expression term ')'

Library/PackageCache/net.gree.unity-webview@ee1c9f516a/Assets/Plugins/WebViewObject.cs(361,19): error CS7036: There is no argument given that corresponds to the required formal parameter 'separated' of 'WebViewObject._CWebViewPlugin_Init(string, bool, int, int, string, bool)'

Observe the syntax error:

        webView = _CWebViewPlugin_Init(
            name,
            transparent,
            Screen.width,
            Screen.height,
            ua,
#if UNITY_EDITOR
            separated
#endif
            );

Start in Assets/Plugins/WebViewObject.cs around lines 361-366 and inspect the platform-conditional arguments at the _CWebViewPlugin_Init call. Reproduce the macOS-target build from the reported revision and compare the call with its required parameters. Done means the build no longer reports the listed CS1525 and CS7036 errors.
