Multiple bugs in attachments.tsx and prompt-input.tsx

[oleics]

Hi,

after a fresh install of shadcn (base) and a subsequent shadcn add ... of some ai-elements components, I've found some bugs:

attachments.tsx

• the AttachmentHoverCard component is broken, openDelay and closeDelay are not defined, and closeDelay does not exist on AttachmentHoverCard

prompt-input.tsx

• the PromptInputActionAddAttachments component is broken as DropdownMenuItem does not have a onSelect property
• same is true for the PromptInputActionAddScreenshot, additionally onSelect has wrong typings
• PromptInputHoverCard is broken in the same way as AttachmentHoverCard from attachments.tsx

conversation.tsx, model-selector.tsx and message.tsx seem to be fine, though.

I took a look into this, and from what I gather I think this may be specific to a shadcn project created with Base UI. The delay defaults in the props for the AttachmentHoverCard component fall back to 0 when undefined so they shouldn't stay undefined at runtime.

It looks like AI Elements expects Radix specific props like openDelay and closeDelay, while the equivalent Base UI components may expose a different API.

Was the project initialized with Base UI? If so my suspicion would be that this is a Base UI compatibility issue.
