Steps to reproduce:

1. Create an empty scene
2. Add a uGUI Text element into Hierarchy
3. Go into playmode

Actual result: Console will report the following warning 'Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak'
Expected result: No warnings or errors

Note that this does not block playmode.
