--- Comment #4 from Don Denton <denton.don at gmail.com> ---
It appears as though the custom property is not what causes this bug as the title suggests. Here is a minimal repro, as far as I can tell:

https://jsfiddle.net/0ph9xkrt/7/

You need the following:

1. a transition is defined that is not instantaneous
2. there is an alpha channel in the color that is *exclusively* between 0 and 1
3. there is at least one color channel which is *exclusively* between 0 and 255

The linked example has some interactions you may observe.
