Emoji preview renders defaultEmoji on initial open without hover

[Amarta113]

Description:

When EmojiPicker is rendered with showPreview enabled and defaultEmoji set in previewConfig , the preview area displays that emoji by default even when the user has not hovered over or interacted with any emoji. This results in a preview being shown on initial render without user interaction.

Steps to reproduce:

1. Select emoji in chat bar
2. Without hovering on any emoji it shows a default emoji and None caption

Expected behavior:

The preview area should remain empty until the user hovers over or selects an emoji.

Actual behavior:
