Multi-select autocomplete does not show any options when there are previous selections

### Description

I have a multi-select autocomplete Pods field on my WordPress site. When I have no saved selections in this field, I am presented with the entire list of options when I click in the input. However, if I already have a saved selection, when I click in the input, no options are shown; the autocomplete functionality (which I think utilizes the Select2 library) seems to think my saved selection is the search.

### Version

2.9.13

### Testing Instructions

1. Create a Pods field with a relationship to another Pod with multiple options.
2. Set **Selection Type** as **Multiple Select** and **Input Type** as **Autocomplete** under **Relationship Options**.
3. Click in the new input field which you created. As expected, a list of all available options for the relationship appear. Typing filters the list as expected.
4. Save the post with at least one selection for the field.
5. Click in the input to add another selection. "No options" is displayed which is not expected. The entire list excluding the saved selection should be displayed and further filtered as the user types.

### Screenshots / Screencast

**Input without any saved selections:**

### Possible Workaround

Not really a workaround but users have to remove all saved selections, save the post, and then add the any new desired options along with the previously saved selection.
