Subject: LP#1768947 Disable offline download button, improve logging
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=9b0fa1aab258395e70123b4e82c4cedb9895b27f;p=Evergreen.git

LP#1768947 Disable offline download button, improve logging

Once the offline block list download button is clicked, it's disabled to
prevent any possibility of double-clicks.  The shared worker also
reports a more meaningful error in case a double-click sneaks past.
