Autocomplete doesn't keep its internal state consistent with jQuery val calls

[emmerich]

Manipulating the contents of an input element with an autocomplete field attached using jQuery.val does not update the autocomplete's internal "term" variable.

JSFiddle here: ​http://jsfiddle.net/qbwdm/

Reproduction steps:

• Type "Hello" into the input box
• Wait for the drop-down
• Press enter
• Value is cleared, drop-down disappears
• Select the input box
• Type "Hello" again (fairly quickly)

Expected:

• Drop-down appears with the correct options

Actual:

• Drop-down doesn't appear

It's because the check in the _searchTimeout (if(this.term !== this._value()) fails, as the internal value was not updated when the .val("") call was made.

Apologies, the ticket seems to has lost some of my formatting around the repro steps.
