Some regressions happened alongside the release of jQuery UI 1.13.0, this brings the fixes from 1.13.1 downstream to WordPress, notably relating to Widget, Autocomplete, Sortable, and Tooltip modules.

See the changelog between version 1.13.0 and 1.13.1 at https://github.com/jquery/jquery-ui/compare/1.13.0...1.13.1

Props blogaid, linux4me2, mgol.
Fixes #54902.
Built from https://develop.svn.wordpress.org/trunk@52648
