QR Code grabber does not work if the dialogue is hidden when a mouseclick is recorded

### Describe the issue

I am trying to activate TOTP on a website that uses a modal box which disappears when clicking with the mouse to mark the area to capture, I assume this would only work if the capture would use the whole screen without a mouse click or if could read the pasteboard directly
