Steps to Reproduce

1. Share.share('text');
2. Select Facebook News Feed
3. Then the Facebook post textfield is empty with the placeholder "What's on your mind?"

It is quite a serious problem because I have been contacted by the Facebook Team regarding this feature which does not respect their policies:

Developer Policy 1.2: Build an app that is stable and easily navigable.Some common violations of this policy include:

• Broken Facebook integration (e.g. broken share, like or comment functionality)
• Broken user experience in the app (e.g. app has broken links or user interface failures)
