'firstItemChecksAll' de-selects some elements in Chrome

[GoogleCodeExporter]

** What steps will reproduce the problem?
1. Create a select with all options selected except the first one.
2. Then call $("#mySelect").dropdownchecklist( { firstItemChecksAll: true } );
3. Open up the page in Google Chrome.

** What is the expected output? What do you see instead?
I would expect the first item to be selected as well as the other ones.

Instead, only the second item is selected and the other ones are de-selected.

After some investigation, it seems that the following line in 
ui.dropdownchecklist.js is causing the problem:
line 781 : sourceSelect.prop("multiple", true);

** What is your environment?
-- DropDownCheckList version: 1.4
-- jQuery version: 1.6.1
-- jQuery UI version: 1.8.13
-- Browser and version: Chromium 12
