Default settings of the Timer effect show alpha background but it isn't fully transparent

SUMMARY
Timer effect is supposed to have a transparent background color according to the default settings of the effect. However, the background is slightly opaque. Once the background color is changed to any other color it cannot be changed back to transparent as there is no alpha setting in the color setting dialog window.

STEPS TO REPRODUCE
1. Create a color clip and put it on the timeline
2. Add a Timer effect
3. Change the background color to any color

OBSERVED RESULT
Timer has a slightly opaque background by default. After Step 3 the background color cannot be made transparent again.

EXPECTED RESULT
Timer has fully transparent background (full alpha). After Step 3 setting the background color back to fully transparent is possible.

I can confirm the issue. Maybe we have to extend the HTML field so we could add #ffffff00. 2 zeros at the end to make the color transparent.
