Toolbar can't override control variant

[hansottowirtz]

Bug description

When using the toolbar to select the "control" variant, it is not overridden but the actual flag is passed.

How to reproduce

1. Create an experiment, make sure the user has a variant that's not "control"
2. Use the toolbar to select "control"
3. onFeatureFlags is called with the variant assigned to the user (not "control")

Environment

/

Additional context

The feature flags are bootstrapped on posthog.init, but I'm not sure if that is relevant.

We're having the same problem with events triggered from addFeatureFlagHandler. The variant will never be control even when flipping between a control and test variant.

We're trying to set up an override that works with locally computed feature flags on the back-end. The only missing piece is to get the correct flags from the toolbar.

I'd recommend using variant overrides inside the UI itself - these are made on our backend, are a lot more stable, and work everywhere, irrespective of the toolbar.

This should be fixed now!
