The Editor slows itself down by showing tons of warnings when the majority of TransformAccessArrays content are NullRefs

Reproduction steps:
1. Open the attached “IN-133271” project
2. Open the SampleScene
3. Enter Play mode
4. Observe the Console and the Profiler

Actual results: The Console logs hundreds of thousands of “Adding null Transform to TransformAccessArray will result in degraded performance” warning and the Profiler shows poor (~33 ms) frame time
Expected results: The Console does not log any warnings and the Profiler shows good (~4 ms) frame times

Reproducible with: 6000.0.47f1, 6000.0.67f1, 6000.3.8f1, 6000.4.0b6, 6000.5.0a6
Not reproducible with: 6000.0.46f1

Reproducible environments: Windows 10 (by reporter), macOS 26.2
