Describe the bug
When changing the alignment of a text block (e.g., left, center, right), the floating toolbar shifts its position in a jarring way. This behavior makes the experience feel inconsistent compared to how smooth it is when aligning images, which do not trigger the same issue.

To Reproduce
Steps to reproduce the behavior:
Go to the editor of blocknote: https://www.blocknotejs.org/

• Type some text into the BlockNote editor.
• Select the text.
• Change its alignment using the toolbar (e.g., click "Right").
• Observe the toolbar "jumping" or misplacing itself.

Misc

• Node version: 22.13.0
• Package manager: npm-10.9.2
• Browser: Firefox-136.0.1 (64-bit)
• I'm a sponsor and would appreciate if you could look into this sooner than later 💖
