问题
I am using jQuery chosen plugin in my project and this issue is happening on trying to edit any input type="password" (deleting the last character in the password field), whenever there is .chosen() binded to any select dropdown on the same page. I could reproduce the issue on chrome browser (version 26.0.1410.43 m), although people have found the issue on Firefox and other browsers too. This happens any page having chosen applied to a dropdown. The issue seems to affect input type="password" fields only. Changing the type to text fixes the UI freeze issue.
So, what could be the main reason behind the issue? I found a similar issue, where jQuery UI is being used -
JQuery UI Dialog: Password inputs causing freezing
So, what approach did you guys follow. There is a work-around in an answer in the above mentioned link which works, but I was looking for a better solution.
