Review fake-selection when creating references

[danicatalan]

Expected behavior When creating a reference inside a Document, there's a functionality called "fake-selection" that must simulate the native browser selection to keep the text highlighted when the user clicks on the sidepanel while he's creating the reference.

What happens There's no fake selection, just the native browser selection, so once the user clicks on the sidepanel to create the connection, the highlighted text is lost.
