This means that now, if you set a value in a context variable before `yield`, the value would still be available after `yield` (as you would intuitively expect). And it also means that you can reset the context variable with a token afterwards.

For example, this works correctly now:

```Python
from contextvars import ContextVar
from typing import Any, Dict, Optional

	buf, err := p.MarshalMsg(data)
	if err != nil {
		return err
	}

	// Saves on all pools to make sure decommissioning of first pool is allowed.
	for i, eset := range pools {
		if err = saveConfig(ctx, eset, poolMetaName, buf); err != nil {
			if !errors.Is(err, context.Canceled) {
				storageLogIf(ctx, fmt.Errorf("saving pool.bin for pool index %d failed with: %v", i, err))
			}
			return err
		}
