I don't think that is the case. Google Docs, Office 365, and Notion all function without requiring repeated user permissions.

I can assure you they’ve correctly described the problem and are correct regarding buffering and user gesture requirements.

The platforms you listed are all primarily text-based and the interaction lives in the DOM with happy paths defined. Still, you will find that clipboard media with a MIME type will prompt you with a Google provided modal to paste a very specific way to get around the permissions model in Google Docs etc…

An RDP interface is not a text box with features on top, the standing expectations for those existing behaviors do not apply. Namely clipboard, and any I/O for that matter. For example, the linked repo uses a protocol bridge (I/O) to support the RDP protocol from a browser, because “the browser speaks protocols” is a true general statement, but absolutely doesn’t apply when you actually need to get something non-trivial done.

At its core, when someone points to the Google Chrome desktop icon and says “that’s the internet” there’s really no point in discussing the nuance in most cases, because anything non-trivial immediately invalidates that understanding of the world and reaching that point organically is far more important than it being explained to them preemptively.

They are correct, because the nuance applies. Welcome to the un-happy path!

There's something about keyboard shortcuts - they work. But somehow right-click and copy requires add-ons.
