Can't make ListBoxSection sticky

[sfc-gh-alisowski]

Provide a general summary of the issue here

I have a virtualized listbox that I want to have sticky sections in. I wrote this custom layout

class StickyListBoxLayout<T, O extends ListLayoutOptions> extends ListLayout<T, O> {
  shouldInvalidate() {
    return true;
  }

  getVisibleLayoutInfos(rect: Rect): LayoutInfo[] {
    const info = super.getVisibleLayoutInfos(rect);
    const stickyItems: Node<T>[] = [];

    // Find the sticky items
    for (const item of this.collection) {
      if (this.collection.getItem(item.key)?.props["data-sticky"]) {
        stickyItems.push(item);
      }
    }

    // Add the sticky items to the layout info if needed
    for (const item of stickyItems) {
      const currentLayoutInfo = info.find((i) => i.key === item.key);

      if (!currentLayoutInfo) {
        const layoutInfo = this.getLayoutInfo(item.key);

        if (layoutInfo) {
          layoutInfo.isSticky = true;

          info.push(layoutInfo);
        }
      } else {
        currentLayoutInfo.isSticky = true;
      }
    }

    return info;
  }

  // Provide a LayoutInfo for a specific item.
  getLayoutInfo(key: Key): LayoutInfo | null {
    return super.getLayoutInfo(key);
  }
}

it find sticky items and makes sure they are still in the layout. this works for items but not sectiosn

Looks to be that the sticky styles are applying to the proper element, but the section's virtualizer div wraps the entirety of its contents (aka the header and the items) when you probably want just the header to be sticky I assume? Sticky virtualizer nodes aren't that well supported and are really only there for Table's checkbox columns so this would be something we'd have to update and would require the Section header structure to be changed I imagine
