Mobile Theme: TextInput with layoutDirection="rtl" becomes mirror on focus out.

After upgrading to version 4.12 TextInput component defined to be with RTL layoutDirection is mirroring the text after focus-out.
When typing the text looks OK, but when leaving the field the text becomes
LTR and in fact becomes mirror writing.
Note that it worked great on version 4.11.

Here is a video the that shows issue.
