[Bug] Safari: non-https site reports undefined is not an object (evaluating 'navigator.clipboard.write')

[wxiaoguang]

Reproduction Steps

• Use monaco-editor on a "http" site (v0.48.0), (do not use localhost, use local IP like http://192.168.1.20)
• Use Safari to open the page, input anything
• Then navigator.clipboard.write triggers the bug

    installWebKitWriteTextWorkaround() {
        const handler = () => {
            ....
            navigator.clipboard.write([new ClipboardItem({ // !!!!!!!!!!!!!! BUG HERE !!!!!!!!!!!!!!!!!!!!!
                    'text/plain': currentWritePromise.p,
                })])
            ....
        };

I have the same problem.

After testing, it can be reproduced from at least version 0.47.0.

The error can be reproduced using the UA of Apple mobile devices and under the HTTP protocol. But it was not reproduced in the dev environment. http://localhost
