During the iOS 9 beta this thread was posted about the tap-and-hold selection menu not appearing on UIWebView text the first time you perform a selection:

This issue still appears on iOS 9.0.2 and can be trivially reproduced with a sample application.
radar issue # is 23181314
Steps to Reproduce:
* Create new Xcode Project using the single-view application template.
* Drag a UIWebView onto the form.
* Create an outlet from the webview to the view controller.
* In the view controller's viewDidLoad (or viewDidAppear) load some HTML:
self.webView!.loadHTMLString("<p>foo bar baz</p><p>foo bar baz</p>", baseURL: nil)
* Run the application.
* Long-press/tap on the html text.
Expected Results:
The text should be highlighted blue AND the selection menu (containing Copy, etc. menu items) should appear.
Actual Results:
The selection menu does not appear. This only happens the first tiem, subsequent selections do show the selection menu.
