Summary:
I create a WKWebView and load data into it. I long press to select text and bring up the context menu.

While the context menu is showing, I create a WKWebView in the background (but never show its view, or add its view to any visible view controller) and load some data into it. As soon as the data finishes loading, the UIMenuController on the visible WKWebView dissappears

Steps to Reproduce:
1. Create WKWebView
2. add it to visible VC
3. Load content into WKWebView
4. Long press on some text to bring up the context menu
5. Create second WKWebView instance, but dont add it to any view or controller.
6. Load data into second WKWebView


Expected Results:
Context menu on first WKWebView should stay in place

Actual Results:
When content is finished loading in second WKWebView, context menu dissappears

Version:
iOS 10.1

Notes:


Configuration:
reproducible on iphone 6+ and ipad air
