Reproduction steps:
1. Open the user's attached project
2. Open BurstBug Script and uncomment 12 line
3. Save the script and observe the Console window

Expected result: No errors
Actual result: Error appears

Reproducible with: 1.4.0-pre.1 - 1.5.0-pre.3 (2019.4.18f1, 2020.2.2f2, 2021.1.0b2)
Could not test with: 2018.4.30f1 (could not downgrade)

Workaround: Accessing through `ComponentDataFromEntity` directly:

```
var cdfe = GetComponentDataFromEntity<Rotation>(true);

Entities
.WithReadOnly(cdfe)
.ForEach((Entity e) =>
{
Debug.Log("blah");
var c = cdfe[e];
})
.ScheduleParallel();
```
