FlowDirection in iOS 12 Simulator [Screenshots]

Description

I am facing a strange interaction when setting the Flowdirection to RTL. If i run the app for the first time (just created), it will show the correction direction. but when i navigate from a page to another or click on the list, some of the components return to LTR direction and never respect the RTL setting even if i removed the app and cleaned + rerun the project.

This happens in iOS only and the MasterDetail menu is still coming from the right which means that not all views lose flow direction.

Steps to Reproduce

1. Create a new project in Visual Studio For Mac with MasterDetail or any template
2. Set the FlowDirection to RightToLeft
3. Notice the interaction in the labels and other components when navigating or clicking on the list.

Expected Behavior

The views should respect the flow direction and not lose it on navigating to other pages or being clicked on.

Actual Behavior

Some views lose the flow direction and never follow it again.
