JSFiddle - React, Tailwind, and code Playground

HTML

<div style="font-size: 12px; font-family: Arial">
    Double click on the different fields.<br/>
    If you get an auto-complete suggestion box, hover on one of its entries (without clicking).<br/><br/>
    The 1st text field will fill the text field with the text of the entry you're hovering on, and <strong>will keep</strong> that text when you stop hovering over it.<br/>Click on the "Check Value" button to see how JS sees the value of the text field.<br/><br/>
    The 2nd text field will fill the text field with the value of the entry you're hovering on, but <strong>will not keep</strong> the text when you stop hovering above it.
</div>
