How to terminate Android ActionMode context menu when Fragment becomes invisible?

Question

Android

There are several Fragments. At the moment, only one of them is visible in the Activity. But there are buttons that switch Fragment from one to another, and you can also return to the previous Fragment using the back button.
For example, one of the Fragments contains a WebView. The user selects a piece of text and a context menu like Copy / Send, etc. appears.
Instead of selecting from the context menu, the user switches the Fragment to another Fragment, and the ActionMode context menu remains hung from the previous Fragment.
I can not understand how to complete the ActionMode when changing fragments?
