onLoadStart
open fun onLoadStart(browser: CefBrowser, frame: CefFrame, transitionType: CefRequest.TransitionType)
Called when the browser begins loading a frame. The frameIdentifer value will never be empty. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method may not be called for a particular frame if the load request for that frame fails. For notification of overall browser load status use onLoadingStateChange instead.
