[UI Bug] Text Wrapping During Streaming Causes Bottom Icon Jitter (Tested on VIVO X200)

[winterdrive]

🐞 Bug Description

On the VIVO X200 test device, a UI issue occurs during streaming text output: when the text wraps to a new line due to
increased length, the icon located near the bottom of the screen exhibits noticeable vertical jitter. It appears that
dynamic height changes in the text layout are pushing adjacent UI elements, resulting in unintended repositioning. A
screen recording is available demonstrating the icon jitter during text line wrapping:
