How to enable the haptic feedback (vibration) within a WebView?

Question

I've been having a look to the built-in haptic feedback you can enable trough the KickBack setting on the Accesibility menu. It works like I expected on most of UI elements.

For those who are not aware of what haptic feedback is, it's very simple, just vibrate slighty as the user presses any button/key/field.

Well, my problem is about enabling that feaure on a WebView interface. I made sure to enable it by calling WebView.setHapticFeedbackEnabled(true), but it wouldn't work. I also tried using the native Android Web Browser, but the haptic feedback is not enabled on there either.

I was wondering if someone has some tip on how to manually set that feedback for the WebView, cause I've been having a look to the API, and can't get any idea.

PD: I'm developing for FroYo on a Nexus One with 2.2.1.

Regards!
