   No, #26 is a different feature request.

   It requires EDT. So I modified the getCookies to use SwingUtilities.invokeAndWait and it seems to fix the problem on Windows and the demo application actually is successfully get the cookies instead of just returning an emptyList

   class WryWebViewPanel(...){
   // ... other stuff
        fun getCookiesForUrl(url: String): List<WebViewCookie> {
           var result: List<WebViewCookie> = emptyList()
           val id = webviewId ?: run {
               log("getCookiesForUrl webviewId is null")
               return result
           }
   
           val action = {
               result = runCatching { NativeBindings.getCookiesForUrl(id, url) }
                   .onFailure { log("getCookiesForUrl failed: ${it.message}"); it.printStackTrace() }
                   .getOrDefault(emptyList())
           }
   
           if (SwingUtilities.isEventDispatchThread()) action() else SwingUtilities.invokeAndWait(
               action
           )
           return result
       }
   
       fun getCookies(): List<WebViewCookie> {
           var result: List<WebViewCookie> = emptyList()
           val id = webviewId ?: run {
               log("getCookies webviewId is null")
               return result
           }
   
           val action = {
               result = runCatching { NativeBindings.getCookies(id) }
                   .onFailure { log("getCookies failed: ${it.message}"); it.printStackTrace() }
                   .getOrDefault(emptyList())
           }
   
           if (SwingUtilities.isEventDispatchThread()) action() else SwingUtilities.invokeAndWait(
               action
           )
           return result
       }
   // ... other stuff
   }

   I'll create a PR with the fix soon once I confirm other platforms are also working
