Alpha Channel of Color of Playhead not doing anything

Hello, as the title says, I’m trying to change the color of the playhead to one more transparent so I can see what’s under it in certain smaller scores that require a lot of zoom.

Under Edit>Preferences>Colors there is a setting specifically for the color of the playhead, but when I change the alpha channel value of it, it’ seems to not get saved: not only there is no visual change but when I open the color picker again I can see the alpha channel always resets to its default of 255.

Is there any way to fix this or to get a transparent playhead?

It looks like the preferences.xml file only stores the color value.

So I would guess that the items in Preferences > Colors ignore the alpha channel value.
