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

[pushkin-]

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?
