Subject: LP#1685840 Activate Google Preview "extras" bar on load
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=refs%2Fheads%2Fuser%2Fbshum%2Flp1685840_dojoless_google_books_signoff;p=working%2FEvergreen.git

LP#1685840 Activate Google Preview "extras" bar on load

Thanks to Ben Shum for pointing out that users might expect the Google Preview
extras bar near the bottom of the screen to trigger loading the preview as
well. Another event listener handles this accordingly.
