   Thanks for the report and the recording — this looks like a real desktop in-app browser bug, and it already has a fix on main.

   What the “Human control” pill is

   That badge is expected. Any trusted click or key in the preview guest is reported as human input and flips the tab to controller: "human" for ~750ms (PreviewManager.handleHumanInput → the pill in PreviewView). It is pointer-events-none and does not intercept copy/paste.

   What actually broke copy/paste

   This is not the old preview clipboard-permission issue (#3738 / #3889), and open #8291 (dropping clipboard-read) is not a fix for keyboard copy/paste.

   #9840 isolated preview keyboard input by setting setIgnoreMenuShortcuts(true) on preview WebContents so host accelerators (settings, close, zoom, …) would not fire. Chromium’s copy/paste/cut/select-all are wired through the application Edit menu, so those chords stopped doing anything in the guest. #9840 was checked on Linux; macOS native editing was left unverified.

   Your build 0.0.40-nightly.20260907.1372 (09e8de9c655a) includes that isolation and does not include the follow-up.

   Already fixed on main

   #10621 (e0e0bcb, merged 2026-09-08) re-enables native editing shortcuts (Cmd/Ctrl+C/V/X/A/Z, plus macOS Paste and Match Style) when the preview (or a sign-in popup) is focused, while still blocking other host shortcuts.

   Please retest

   Install a desktop nightly after e0e0bcb / #10621 and try copy/paste in the in-app browser again.

   • If it works, we can close this.
   • If it still fails, say whether you used keyboard shortcuts, the Edit menu, or right-click — and we will look at webview focus / guest context-menu next. macOS 27 Beta is a possible leftover only after that newer build.

   @juliusmarminge Yeah, I tried the latest nightly, copy/paste shortcut works now. Just that there is no right-click, but not a big deal anyways, and probably out of the scope of this issue anyway.
