HTML: "Copy link address" fails with "Document is not focused"

[benbucksch]

Reproduction

1. Open an HTML email
2. Right-click on a link / URL
3. Select "Copy link address" menu item
4. Paste in another app, e.g. a text editor

Actual result

• Nothing is copied
• No error msg is visible to end user
• Console shows error "NotAllowedError: Failed to execute 'writeText' on 'Clipboard': Document is not focused."
• Stack trace

  at copyToClipboard (../../../../app/frontend/Shared/ContextMenu.ts:264:25)
  at copyLink (../../../../app/frontend/Shared/ContextMenu.ts:226:3)
  at menuItem (../../../../app/frontend/Shared/ContextMenu.ts:38:56)
  at catchErrors (../../../../app/frontend/Util/error.ts:60:11)
  at <object>.click (../../../../app/frontend/Shared/WebView.svelte:145:20)
...

Expected result

• The URL is pasted
• On Linux, the secondary clipboard is used (the clipboard where I explicitly copy and explicitly paste something, not the clipboard where every selection is copied and a mouse middle click pastes it)

Additional info

• "Copy" on a selected text works, with the secondary clipboard, as expected

@jermy-c Have you tried focusing the right document? Given that writeText() is called by the frontend, it should probably be the frontend and not the webview that is focused. A simple document.documentElement.focus() - or similar - might be sufficient. Can you please investigate in this direction?

[jermy-c]

I have tried:

• document.documentElement.focus()
• <webview>.focus()
• window.focus()
• webcontents.focus()

It be because the while the context menu is in the backend and while the function is executing it will focus on the window it is called.

Chrome

Document is not focused

This error happens in Chrome when there is delay in writing to clipboard and user is not focusing on the window.
