[FIX] web_editor: cursor position wrong after link in safari

Before this commit:

For the safari browser, when typing any URL and pressing space, and
continuing typing, the cursor jumps before the URL.

After this commit:

Inserting an element into a range clears the selection in Safari.
Hence, use the cloned range to reselect it and now the cursor position remains
at the end of the URL.
