Custom palette colors don't work

Description

A user reported that he wanted to use a custom palette color for the link hover and it wasn't working in frontend (https://vertis.d.pr/v/dIUuXq). I checked and the custom palette colors work until the editor is saved https://vertis.d.pr/v/9GfLqk

Reported here - https://wordpress.org/support/topic/custom-colors-registered-in-the-style-are-not-working/

Step-by-step reproduction instructions

1. Add new custom colors in the palette
2. Use them for Text/Background/etc as you see in the video
3. Check if it works in frontend

Environment info

WordPress 6.4.3 / Raft 1.1.2

Is the issue you are reporting a regression

No

Reproduce the issue in WordPress 6.4.3 with Raft 1.1.2 using the linked videos and the listed palette steps. Compare the saved editor output with the frontend rendering; done means registered custom colors still apply to text, backgrounds, and link hover after saving.
