Subject: Fix blur/focus handling in autocomplete.js
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=02b80e99b3db5f00a7e7ed75100e997338ffa3fa;p=horde.git

Fix blur/focus handling in autocomplete.js

document.activeElement does not work in all browsers, but it is the only
way to reliably get focused element.  Works on all recent browsers.
