MissingReferenceExceptions are thrown when changing UI parent Canvas to disabled Canvas during play mode
How to reproduce:
1. Open the "SampleScene" in the attached "case_1171433_Repro" project
2. Press "Play"
3. Select any of the dropdown menu elements
Expected results: Dropdown will become invisible, as the new parent Canvas is disabled
Actual results: MissingReferenceException errors are thrown
Reproducible with: 2019.1.0b1, 2019.1.14f1, 2019.2.01f1, 2019.3.0a11
Not reproducible with: 2017.4.31f1, 2018.4.6f1, 2019.1.0a14
Additional notes:
The warnings about missing script under the Main Camera GameObject do not cause these errors and can be safely ignored if they are thrown.
