Autocomplete Combobox memory leak

Reported by: Adam Jimenez Owned by: Scott González
Priority: minor Milestone: 1.12.2
Component: ui.autocomplete Version: 1.12.1

There appears to be a memory leak with the autocomplete combobox. I can recreate it by going to the combobox demo in Chrome (54):

And then clicking the "show all items" button over and over. After around 50 times it starts to noticably slow down, keep going and it eventually slows to a crawl.

This is more apparent in my real world app, which is often left open for a long time and can contain many more autocomplete items.

I am facing the same problem with my own jQuery-UI widget based on the widget factory and using the autocomplete widget internally.
But it is also reproducible with a simple test case (local source with 50 items and no filtering):

  • Tested on latest Chrome (57.0.2987.110) and Edge (38.14393.0.0)
  • Tested with latest jQuery (3.1.1) and latest jQuery-UI (1.12.1)
  • Reduced test case:
  • It takes about 10x more time for the suggestion list to be displayed after 30 openings on Chrome

Additional notes:

  • Firefox (52.0.1) is not affected
  • jQuery-UI (1.12.0) is also affected, but less importantly
  • jQuery-UI (1.11.4) is not affected

Edit: Seems to be related to other performance tickets already opened:

Edit 2: There is a workaround as described by jGeek314 in 10050 :

search: function(e,ui){
  $(this).data('ui-autocomplete').menu.bindings = $();
