Fix live-mode link navigation not selecting the target link

In live mode the DOM is rebuilt from the device when switching sheets,
creating new element objects. The pending link from the old tree could
not be found by identity in canvas_link_map. Re-resolve it by from/to
attributes after the rebuild so the selection matches.
