demo project

On tablets I use a MasterDetailPage with MasterBehavior=Split. So the iPad should display Master and Detail side by side in portrait and landscape.

But when my iPad Pro 9.7" is in Split Screen mode, then it only displays Master or Detail. In landscape, when my app has 50% of the screen, then it only displays the Master. When it uses 75% of the screen, then it only displays the Detail page. In portrait, it only displays the Master.
In any case I couldn't find a way to switch between pages.

I tested this with Xamarin.Forms 2.3.4.247 and 2.3.5.256-pre6. The attached demo project uses the latter.

I'm able to reproduce this issue with the attached project and the issue still occurs with the Forms 2.3.6.116-nightly build. 

I'm seeing the same behavior as mentioned in the description when using the iPad multitasking split view and there is no way to get the other view if only the Master or Detail is shown:

### Portrait
Full:   Master and Detail visible
Split:  Master only

### Landscape
Full:   Master and Detail visible
75%:    Detail only
50%:    Master only

The same problem is when MasterBehavior=Popover. Curentlly MasterDetailPage is not working correctly in Split Screen Mode on iPad.
When this problem will be resolved?
