Dragging text into page doesn't lead to search engine picking it up but instead outputs "The address isn’t valid" error
Open Tor Browser, go to https://blog.torproject.org for example. Have some text in a text editor ("search query"), select it and drag it to the page (and not the tabs or something near that), normally this would lead to default search engine processing it and loading search engine page, but instead it outputs "The address isn’t valid" error.
