bug(textarea): Unexpected Enter Key Triggering with Modifier Keys

[h2ls]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

Description:
When pressing keyboard shortcuts involving modifier keys (e.g., Ctrl+Enter or Shift+Enter), the current keyup event handling logic still triggers the Enter key callback method, leading to unintended behavior. The expected behavior is to ​only trigger the callback when the Enter key is pressed alone (without any modifier keys).

Expected Behavior

The callback should ​only fire when the Enter key is pressed alone (without Ctrl/Shift/Alt/Meta keys). Any modifier key combination should be ignored.

Interactive render mode

Interactive Server (Interactive server-side rendering (interactive SSR) using Blazor Server)

Steps To Reproduce

1. Bind the "OnEnterAsyncevent" to a textarea using handleKeyUp.

2. Press Ctrl+Enter or Shift+Enter in the textarea.

3. Observe that the enterCallbackMethod is unexpectedly triggered.
