Description

As of very recently, there is a new "Asynchronous Clipboard API" available for allowing webapps like Guacamole to read/write the clipboard pretty much exactly like we've always wanted:

https://www.w3.org/TR/clipboard-apis/#async-clipboard-api

Users are prompted whether they wish to grant the page access, and their answer is remembered going forward just like the other various things users can grant access to (audio input, for example).

This API is available in Chrome 66+:

https://developers.google.com/web/updates/2018/03/clipboardapi

A pair of flags must currently be enabled for the API to be available:

• chrome://flags/#enable-experimental-web-platform-features
• chrome://flags/#clipboard-content-setting
