Read only Editor is editable when Next from on screen keyboard

[DennisWelu]

Description

If you have a read only Editor after an Entry field with ReturnType="Next", the on-screen keyboard will both enter you into the Editor AND it will be editable. This only happens if focus is shifted from the on screen keyboard. Tap into the Editor directly and it works as you would expect.

Steps to Reproduce

Just add both an Entry and an Editor to your UI like this:

<VerticalStackLayout Spacing="25">
            <Entry Placeholder="This is editable" ReturnType="Next" />
            <Editor Placeholder="This is read only" IsReadOnly="True" />
</VerticalStackLayout>

Then run...

Tap into the Entry, see the on screen keyboard appear. Tap "Next".

Observe that you can now edit the read only Editor text.
