[Problem/Bug]: Can use pre-release FrameCreated event even against the stable runtime

What happened?

I'm using the Frame::FrameCreated event added in the 1.0.3079 pre-release which says:

For full API compatibility, this Prerelease version of the WebView2 SDK requires the WebView2 Runtime that ships with Microsoft Edge version 134.0.3079.0 or higher.

I don't recall this being the case last I tested, but now I'm seeing that event fire even when using the stable version of the runtime (I uninstalled the canary runtime completely)

Is this an issue? I thought I'd have to use Canary for this event to fire. Is that not the case?

Importance

Low. My app is not very affected, or this only affects development.

Begin by comparing the documented Frame::FrameCreated compatibility requirement with the reported WebView2 SDK 1.0.3079 pre-release and stable runtime 133.0.3065.69 on Windows 11. Reproduce the behavior if possible; done means establishing whether the event firing on the stable runtime is expected or a compatibility bug.
