Bug: Swiftkey blocks Email app from adding attachments...

1.) Using attached bluetooth keyboard

2.) Virtual Keyboard (disabled) 

3.) The prediction bar seems to block (?) Android's stock Email App from opening any attachment pane -- Gallery, Doc or Other...

The workaround:

1.) Temporarily enable the virtual keyboard in SETTINGS. 

2.) Click on "Attach".

3.) Choose attachment.

4.) Disable the virtual keyboard in SETTINGS.  

Why does Swiftkey stubbornly refuse to allow users to option to disable the prediction bar globally or for given apps?
