[Problem/Bug]: Hololens Unity EventType.MouseMove not working

What happened?

Hi

I have been able to integrate the Hololens WebView SDK into Unity with working mouse up and mouse down events. I cannot seem to get hover effects on pages to work using the WebViewMouseEventData.EventType.MouseMove event type.

I've tried to dig around and see if anyone has tried to enable this functionality to no avail. I assume it is because Hololens is not really intended to be used with a mouse per say?

I understand this is not officially supported outside of a Hololens environment, but the runtime as is runs almost perfectly for integrating into Unity as a general web browser. (I intend to use it to present UI and such).

I can ensured the inputs are correct so at this point I can only assume it's intended and just missed out of the native libraries built to wrap WebView2 functionality.

Any help you could give on this would be greatly appreciated.

Regards
Dan

Repro steps

Follow the steps outlined in https://learn.microsoft.com/en-us/microsoft-edge/webview2/get-started/hololens2#step-4---install-the-webview-plugin-for-unity-by-using-the-mixed-reality-feature-tool. And then create an event for Mouse Move events, plugging in the corrected Unity mouse position coordinates. Hover effects etc don't work, but click events do.

Regression

No, this never worked

Last working version (if regression)
