[Support request] RGBA colors instead of hex?

Hi, at some point in the past GeneratePress supported the use of RGBA colors instead of hex for text/link colors – I have some headers set up in Elements that use rgba link colors so that the current page is 100% opacity and others are dimmed slightly to look good with a featured image background. Now when I go into the elements, trying to edit the color resets it to default hex values (no transparency). Trying to paste rgba values into the customizer for link colors trims the string to 7 characters and highlights it as an error.

Is there any way to get this functionality back? Now updating any of my header elements will lose the transparencies I’ve set up. It’s especially annoying because rgba values still work for background overlays, they just no longer work for text color/link color. I understand I can override the values with custom CSS, but part of the appeal of elements was being able to set up these types of rules for colors etc without needing to override them manually.
