This fixes it so that keyboard navigation should work when loading a book from a
file://
url.When loading the search index, if it fails due to a CORS error (such as when loading json from
file://
), it will load thesearchindex.js
version instead here. However, this was written to replace thewindow.search
object which loses thehasFocus
method which caused the keyboard handler to fail becausehasFocus
was missing.This changes it so that instead of replacing
window.search
, it just updates the existing object.Fixes #910.
