Steps to reproduce the problem:
1. 
2. navigator.share is not undefined in desktop mac chrome
3. 

What is the expected behavior?
navigator.share suppose to work on devices where the native sharing apps are available so that user will select the sharing app based on the user pref

What went wrong?
But in Mac Chrome , where there is no such option to open sharing dialog, is having navigator.share defined , making it difficult to check the functionality for devices where the native sharing dialog is supported

Did this work before? N/A 

Does this work in other browsers? Yes
