Fixes #30426. Using `abs` here is probably better than any solution based on `clip` or `maximum`, because it maintains differentiability in the valid regime. I'll run some additional tests before merging this in order to ensure that it doesn't change numerics in important contexts. PiperOrigin-RevId: 836332119
