Pressing 'Enter' causes error

[adaptedbee]

Description

1. Click the tooltip icon
2. Not focusing into input field, press 'Enter'.

Environment

• Editor.js version: 2.29.1
• editorjs-tooltip version: 1.2.2
• Device, Browser, OS: Desktop, Google Chrome 128.0.6613.137, Windows 10

Current behavior

'Enter' works on selected word. Line breaks, selected word disappears, tooltip creates with empty word and undefined attribute.

Expected behavior

Prevent user from press Enter, when not focused on input field. Maybe autofocus into input field.

I’ve opened a PR that fixes this issue by:

• Auto-focusing the tooltip input when opened
• Preventing the Enter key from bubbling to Editor.js unless the input is focused

This prevents selection loss and undefined tooltip values.
