Reflection probe bounces don't work when Rendering Path is set to 'Deferred'

Global Illumination

-

How to reproduce:
1. Open user-submitted project (ReflectionProbeTest.zip)
2. Open the SampleScene
3. Select the 'Reflection Probe' GameObject and click 'Bake'

Expected result: the reflection bounces work properly
Actual result: the reflective sphere shows up as black

Reproducible with: 2018.4.24f1, 2019.4.2f1, 2020.1.0b15, 2020.2.0a16

Notes:
Changing Rendering Path in the Graphics Settings for High(Tier 3) from 'Deferred' to 'Forward' yields the expected result

    Resolution Note (fix version 2021.1):

    This issue was caused by the ReflectionsToEmissive pass using the incorrect backface culling when rendering the reflection probes on the deferred path.

    Fixed in 2021.1.0a1

    The PR https://ono.unity3d.com/unity/unity/pull-request/113299/_/graphics/deferred-reflection-probe-reflections-fix should fix this issue.
