 When copy pasting using the Async Libre API, the unsanitized option for the read method allows apps and websites to get unsanitized HTML. Unless sites include this property, reading HTML from the clipboard will be sanitized. By default, when reading text HTML mind types using the Async API, the sanitizer is invoked to strip out contents from the HTML markup due to security concerns and styles are in line in the resulting HTML. This leads to a large HTML payload and loss of fidelity of HTML content when read by web developers or mobile apps. You can see the difference in the output with the code on the screen.
