The link inspector ignores the text entered when the user does not wait for the "matching page" results to appear (Chrome/Ubuntu) before pressing "enter". If the user is adding a completely new link, the selection appears offscreen and we get a JavaScript error:
Uncaught Error: No class registered by that name: undefined
This behavior is similar to earlier issues such as bug 42278 and bug 49941.
