[bug] Cannot insert line break in text element using Enter, Ctrl+Enter, or Command+Enter

[spartan-uyen]

Summary:
Text elements do not accept line breaks. Pressing Enter (or modifiers like Ctrl/Command + Enter) has no effect, preventing multi-line input.

Steps to reproduce:

1. Select a text element on the canvas.
2. Begin editing the text.
3. Press Enter, Ctrl+Enter, or Command+Enter to insert a new line.

Actual result:
No line break is added.
The text remains on a single line, regardless of key combination used.
