Do the following:
- Select the top most element, you want to copy. (To copy all, select
<html>
)
- Right click.
- Select Edit as HTML
- New sub-window opens up with the HTML text.
- This is your chance. Press CTRL+A/CTRL+C and copy the entire text field to a different window.
This is a hacky way, but it's the easiest way to do this.
