Wiggle expression on rotation no longer seems to work properly

I'm not sure if I'm inadvertantly doing something wrong here or if the wiggle expression is broken in AE 24.3.0, but I used to add an expression like:

wiggle(4, 0.05)

to the rotation of a layer. It would rotate 4 degrees either way 0.05 times a second, giving me a nice, smooth, slow wiggle rotation.

However, now anything under 1 second in the wiggle expression just makes it jiggle from positive zero to negative zero (whatever that is). And anything over a second is way too fast for a rotation wiggle, when I'm just trying to add some natural looking movement to something.

Am I doing something wrong? Or is this expression broken now?
