How to reproduce:
1. Open the user-provided "VuforiaSample.zip" project
2. Build the project for HoloLens (UWP platform)
3. Open the produced .sln solution file with Visual Studio
4. Build on Remote Machine - HoloLens device (Debug | x86 | Remote Machine)
5. Once the application launches, in HoloLens, click "Image Targets" in the Menu
6. Open "Astronaut_scaled.jpg" on your computer and show it in front of the HoloLens camera
7. Wait for the digital overlay to appear on the HoloLens
8. Move slightly to the side and say "Load Scene" or do a hold tap to trigger the additive scene load
-- now the digital overlay is moving accordingly but with an offset (translated and rotated)

Expected result: After the "Load Scene" command, when additive scene load is triggered, an offset is NOT introduced to the digital overlay.
Actual result: After the "Load Scene" command, when additive scene load is triggered, an offset is introduced to the digital overlay.

Reproducible with - 2019.1.0a12, 2019.1.0f2, 2019.2.0a12
Not reproducible with - 2018.3.0b1, 2018.3.13f1

Could not test on 2019.1 versions before 2019.1.0a12 due to errors.

Note:
- On 2018.3, the app launches in the windowed mode and the digital overlay does not match the size of the original image. However, after the "Load Scene" command, no offset gets introduced (the issue does not occur).
