Description

This hinders copy pasting from a webview. The bug wasn't there in 6.2.2.

To reproduce, apply the diff below to the MarkDown Editor example. Run the app, select some text from the webview on the right, copy it (Ctrl+C), then select File > New.
Observe the extra text at the start of the HTML:
