Autocomplete: Doesn't reset after Select when textbox cleared, if same letters typed in rapidly; source function not triggered in that case

Observed using IE 8. Setting: minLength: 2

I am using a single textbox / autocomplete to create a list. The list is handled outside of the textbox autocomplete functionality, except that I have autocomplete's Select functionality send it outside of textbox and autocomplete.

I am returning false from the ''Select'' function. And within the Select function I am clearing the textbox (setting to "").

Imagine I want to select John Smith the first time and John Doe the second time. I type in "jo" and the ''source'' function is triggered. I then select John Smith. It goes fine. The ''Select'' function is triggered and clears the textbox. Then I again type in "jo" with a fast typing speed. In this case the ''source'' function is not triggered. If instead I type in "jo" with a slow typing speed, the ''source'' function is triggered. If I instead type in "su" or any other two letters at a fast or slow speed, the ''source'' function is triggered.

I am working around this by putting my initializing source and Select functions in a reset function and in my Select function I am using the AutoComplete destroy method and then calling my reset function.

Maybe this is not a bug but I am submitting it in case it is.
