Fix auto-selection of URL field with X11 selection
We use `focusin` event instead of `click` because when using the latter, when the selection is created it isn't put into X11 PRIMARY selection. And as a Linux user I'm very used to such behaviour that when something gets selected, it's ready for pasting, which is the primary purpose of the clone URL field. When `focusin` is used, the selection is copied to X11 buffer automatically, so it works as expected (tested in Firefox and Chrome).
