What are you trying to accomplish?

In a previous PR, I added functionality to ensure that pressing Enter while focused on the filter input of a SelectPanel selects the first list item, in accordance with our API docs for the component. However, the methodology I chose did not account for the case when list items are links, i.e. anchor elements. This PR simulates a click event instead, so everything works as expected even when list items are links.

Screenshots

The video below shows that pressing Enter while focused on the filter input navigates to the URL specified in the anchor tag for the first list item, which is https://github.com.

I tested in Lookbook and discovered a niche bug. In the single select playground example, if you select an item via the input, then filter the input by some text and select a different item, both items are selected when you reopen the panel.

Still seeing the same issue:

CleanShot.2024-07-30.at.16.07.32.mp4

Alt: On storybook SelectPanel/playground I navigate to an item using the search field. I check that item. When I reopen the SelectPanel two items are selected even though I am in a SingleSelect.

Alright, we ended up removing the piggybacking code designed to fix issues where a user's selections would be overridden by server-rendered selections. This PR now only contains fixes for the issue in the title + description.
