Spec https://w3c.github.io/pointerevents/#the-button-property

https://cdn.rawgit.com/w3c/uievents/gh-pages/index.html#dom-mouseevent-button

No Tag review, was already in spec for a while but not implemented.

Summary

Send mouse events (pointerdown, mousedown, auxclick, pointerup, mouseup) for back and forward buttons on mice with 5 or more buttons..

Link to “Intent to Implement” blink-dev discussion

Intent to Implement

Is this feature supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?

Yes

Demo link

https://rbyers.github.io/eventTest.html

Debuggability

Relatively easily debuggable; monitorEvents is handy here.

Risks

Interoperability and Compatibility

Edge: No signals

Firefox: Some support

Safari: No signals

Web developers: Has been requested by a few people, but no public requests. One specific website is https://remotedesktop.google.com/ that will have an improved UX.

Ergonomics

None from the API point of view.

Shipping this feature requires a UX change for Linux and Chrome OS which has been approved by the Chrome Launch process in that the activation of the back/forward event is done on the mouseup instead of the current mousedown. This is so that the default event behavior is consistent across all operating systems.

Activation

Available immediately.

Is this feature fully tested by web-platform-tests?

Yes

LGTM with question below.

To be clear, this only affects when using the back/forward buttons, not other back/forward navigations, right?

Activation

Yes that is correct, only navigation with the back/forward mouse buttons change.
