<Pressable to={externalUrl}> correctly adds target="_blank" to the <a/> in the editor, but live in production it’s missing both target and rel attributes, so the link opens in the same tab, even though the url is external.
For full reproduction, use the following code.
<Pressable to={externalUrl}> <-- this opens in the same tab
<Button
kind="secondary"
onPress={() => console.log("clicked"))
activateTarget="custom-text"
activateAction="copy"
>
copy text and go to page
</Button>
</Pressable>
<ClipboardItem text={"copy me"} id="custom-text" />
