Hello and thanks for reporting.

Do you have an example of an app/webpage combo that exhibits this bug?

@rjwright

We'll be publishing out app soon (within a week or two), which will be a good example. 

As of today, I believe that the Facebook app is built in React/Cordova which would mean it is entirely a webview.  In this app the cursor changes to a "text select" style when hovering over text areas, but does not change to a "pointing hand" style when hovering over buttons and links.  

Thank you for providing more feedback. Adding requester "rjwright@chromium.org" to the cc list and removing "Needs-Feedback" label.

Here's a better example.  

App: "PhET Sims presented by Kiwix" https://play.google.com/store/apps/details?id=org.kiwix.kiwixcustomphet&hl=en

When you open the app, select the simulation called "Balancing Act".  Notice that when your mouse hovers over any of the three initial choices ("Intro, "Balance Lab", or "Game"), that the cursor style does not change.  However, the WebView does somehow receive a mouseover event because there are highlighting rules that do take effect.

Now go to the same web page (https://phet.colorado.edu/sims/html/balancing-act/latest/balancing-act_en.html) in a browser, even Chrome on ChromeOS, and notice that when you hover over the same objects the cursor changes to a pointing hand style.
