When some code is frequently changes opacity of some object, onMouseOut of that
object not fires. This trouble arise then mouse pointer stay on object at least
2-3 seconds. I noticed that problem arise then delta (of opacity) is added to
current opacity - some_object.style.opacity (see attach, line 40). If I write
"some_object.style.opacity = some_object.style.opacity" (without adding delta),
then onMouseOut occur correctly, but without necessary functionality. So, the
summary: at intensive opacity changes event onMouseOut not fires.

Reproducible: Always

Steps to Reproduce:
See attach

Seems to work fine for me in the latest nightly trunk build.
Could you please test again with the nightly trunk build?
