Description

I am trying to use Selectivity.js for a multi-select on a form with several other inputs. Upon submission, when the form is redisplayed (because of validation errors in other fields), I display the previously selected options back by using "selected" in those options.

Now, if I try to remove any of the options I had selected in the previous step and resubmit the form, the removed options continue to be selected. And that is understandable, because clicking the remove icon does not remove it from the element. How can I make the removed items also removed from the element. Or is there another way to accomplish this.

Thanks!

Research direction
The issue is that removing a selected option from the UI does not update the underlying <select> element. Investigate the Selectivity.js source code to understand how it handles removal of selected items. Look for methods like `removeItem` or event handlers for the remove icon. Check if the library syncs with the original <select> element. The fix likely involves ensuring that when a selected option is removed, the corresponding option in the <select> is also deselected or removed. Consider the library's documentation or source files such as `src/selectivity.js` or `src/selectivity input.js`.
