The sun on 1.21.90 has missing glow gradient blend around it

The two images show a visual bug with the sun texture in Minecraft Bedrock Edition, comparing the original look (pre-1.21.90) to the broken version (post-1.21.90 update):

Pre-1.21.90 (First Image):

The sun has a soft glow effect and gradient blending into the sky.

It appears natural and visually polished, matching the overall art style of the game.

Post-1.21.90 (Second Image):

The sun is rendered as a solid white square with no glow or gradient.

It looks visually harsh and out of place, indicating a likely texture or shader bug introduced after the update.
