Style update ignores custom darkmode colors

[cls-design]

If you update a style without darkmode with a version that has its own darkmode palette, the style will have a darkmode after the update, but only with the standard palette.

Edit:

A style update generally doesn't update colors, does it? To not overwrite the user customizations?

With an update from no darkmode to darkmode it would make sense to take over the colors, otherwise it is more likely that the darkmode after the update with the standard colors does not look like it should or in the worst case the darkmode becomes unusable.
