I have got a simple tree component on my page similar to the following:

<tree id="treeOriginal" droppable="false" vflex="1" multiple="false" checkmark="false" >
  <treecols sizable="true">
    <treecol hflex="1" />
    <treecol width="32px" />
    <treecol width="32px" />
    <treecol width="32px" />
    <treecol width="44px" />
  </treecols>
</tree>

The tree is later filled with content. Generally, the component is working well. However, when I'm expanding one of the nodes within the tree. A vertical scroll bar is displayed for flashlike - i.e. I can scroll with the scroll wheel of my mouse but after the flashlike display of the scroll bar I don't see it any longer.

Most interestingly, the problem exists in Chrome but not in Firefox (haven't tested Edge so far). Any ideas how to work around this problem?
