Bug: Dropdown misplacement after scrolling

Lexical version: v0.12.4

## Steps To Reproduce

1. After package deployment, add the lexical editor to the necessary location.
2. Assuming the lexical editor is not at the top of the page but rather positioned at a specific part of the page after scrolling, when the toolbar's dropdown button is clicked, the dropdown appears not directly at the bottom of the toolbar but somewhere in the middle of the page.

## The expected behavior

No source file or test is identified. Start by reproducing the issue with Lexical v0.12.4: place the editor below the top of the page, scroll, and open the toolbar dropdown. Done means the dropdown appears directly below the toolbar after scrolling, matching the expected behavior.
