Pressing Ctrl/Cmd+Enter in Color field no longer adjusts other color values proportionately with live color preview since 27.1.1
Prior to 27.1.1, when live color changes were made, we were able to use Ctrl/Cmd+Enter after changing a value to proportionally move all other sliders, which is an equivalent of dragging a slider with Ctrl/Cmd key held.
The face the preview is now live should not kill this old feature., since Ai surely can remember previous values.
