No suggestion if try to re-define css variable

[Yegorich555]

One of the important feature of css-vars is ability to re-define value of existed css variable. Lets assume I need to rewrite --base-bg: #fff;
So when I type -- I'm expecting to see list of vars

button {
   --base-bg: #fff;
   background: var(--base-bg); /* intellisense suggests css-var here - it worksF */
}
.customButton {
   --base-bg: #efefefe; /* when I type  --b  intellisense-list is empty; but expected the same behavior as above */
}
