[Bug] Caret causes text aligned center or right to be misaligned

### Bug Description

Aligning a paragraph block center or right causes text to be misaligned when the caret is focused on the paragraph block. Moving the caret to another block makes the alignment correct.

### How to Reproduce

1. Input text to an AppFlowyEditor widget.
2. Set alignment to center or right, see the text misaligned
3. Move the caret to another block (or create a new one by adding a newline)

### Expected Behavior

Alignment should be preserved even if caret is present.

### Operating System

Windows 11 (26200.5074)

### AppFlowy Editor Version(s)

6.0.0 (main branch from repository), Flutter 3.35
