Description
When editing long text content that exceeds maximum height constraints on iOS, manipulating text in the upper region causes scrolling jitter. The view incorrectly scrolls to the bottom while keeping cursor position at the top.
This issue occurs consistently (100% reproducibility) when rendering text as children and using refined values, such as in chat applications with mention functionality. The problem can also manifest when inserting empty lines in the upper portion of the text area.

Research direction
No file, test, or entry point is identified. Reproduce the issue on iOS with long text rendered as children, refined values, or inserted empty lines, then trace the text-input scrolling behavior; done means upper-region edits keep the cursor visible without jumping the view to the bottom.
