Description
#### Environment details
- OS type and version: MacOS 26
- Python version: Python 3.12.11
- pip version: uv
- `google-api-python-client` version: n/a
#### Steps to reproduce
Intermittent HTTP 400 / preconditionFailed on Gmail API. A casual web search suggests that other Google APIs also issue preconditionFailed. At least in my use case, retrying with exponential backoff always works. I cannot assert that in all use cases that this is the correct behavior.
