Need a possibility to change size of listheaders of listbox element by splitter.
Need to add class to splitter to use it in listbox as in tree case. In instance:

<listbox flex="1">
  <listhead>
    <listheader label="header1"/>
    <splitter class="list-splitter"/>
    <listheader label="header2"/>
  </listhead>
  <listcols>
    <listcol flex="1"/>
    <listcol flex="1"/>
  </listcols>
  <listitem>
    <listcell label="cell1"/>
    <listcell label="cell2"/>
  </listitem>
</listbox>

It's not going to work. Unlike a tree whose treecol elements both govern the
display of the tree and are themselves visible elements, the listcol elements
are invisible and therefore cannot have splitters, while the listheader elements
are visible but don't affect the display.

Maybe it is difficulty to add a splitter (ability of columns resize).

Sometimes listbox is more convenient than tree but tree will be used instead of
listbox (in case that ability of columns resize isn't presented) in spite of the
fact that listbox is more convenient.

Area of listbox application is coincided with area of select html element with
specified attribute size.
