Setting enabled = true to RichTextEditor shows disabled color only for uncolored text parts

[Sermilion]

When setting RichTextEditor's enabled = false, text color changes to disabled color, which in theory makes sense. However, if we set a text that has some color specified, only the part with default color will change to disabled color, and the rest of the text that has "rich" color, will remain the same. See attached image - red color is unchanged and only uncolored text has disabled color variant.

SOLUTION:
Ideally, we would apply alpha value to whole text and then we would see disabled state for the whole text with alpha value applied to each color.
