[seon1994]

Bug description

1. [flow-lineage] last child node is not visible
2. [flow-lineage] when fold the children-toggle, some of the child nodes disappear

Reproduction steps

1. [flow-lineage] last child node is not visible

• You can check it here : https://flow.ollion.com/v2/index.html?path=/story/ollion-flow-lineage-f-lineage--playground
• If you remove mchild12 to mchild16 of the MAX node, mchild11 is not visible on the screen.
• As expected, up to mchild11 should be displayed, but up to mchild 10 is displayed.

2. [flow-lineage] when fold the children-toggle, some of the child nodes disappear

• You can check it here : https://flow.ollion.com/v2/index.html?path=/story/ollion-flow-lineage-f-lineage--playground
• If you fold the children-toggle, some of the child nodes will disappear.
• If you lower the scrollbar of the MAX node to the bottom > fold > expand > scrollbar to the bottom, some of the mchild disappears. Since mchild has disappeared, the scrollbar also looks awkward.
• As expected, mchild does not disappear and is still present.
