Missing css-variables of `graph-block-anchor` for width and height

[ma-efremoff]

Current behavior:

.graph-block-anchor {
    --width: var(--graph-block-anchor-width, 16px);
    --height: var(--graph-block-anchor-height, 16px);
    width: 16px; // duplicated !!!
    width: var(--graph-block-anchor-width, 16px);
    height: 16px; // duplicated !!!
    height: var(--graph-block-anchor-height, 16px);
    ...
}

<div class="graph-block-anchor graph-block-anchor-out graph-block-position-absolute"
     style="--graph-block-anchor-x: 320px; --graph-block-anchor-y: 65px;">
    ....
</div>

At the moment the library provides values for --graph-block-anchor-x and --graph-block-anchor-y.
It would be convinient if the library provided also sizes:

• --graph-block-anchor-width
• --graph-block-anchor-heigh

Is it possible to implement it?
