When placing a menulist with a menupopup inside a deck which itself is included in  
a box with css rule "overflow:scroll", if you scrolldown and click the menulist,
the menupopup is misplaced. If you place a tree in the same position, selecting
a treechildren is misplaced as well.

<window xmlns:html="http://www.w3.org/1999/xhtml"
        xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">

    <vbox flex="1" style="overflow:scroll;">
        <description value="some content" height="400" minheight="400"/>
    
        <deck selectedIndex="0" flex="1">
            <vbox>
                <menulist label="Bus">
                    <menupopup>
                        <menuitem label="Car"/>
                        <menuitem label="Taxi"/>
                        <menuitem label="Bus" selected="true"/>
                        <menuitem label="Train"/>
                    </menupopup>
                </menulist>
                <tree flex="1" minheight="300">
                  <treecols>
                    <treecol id="sender" label="Sender" flex="1"/>
                    <treecol id="subject" label="Subject" flex="2"/>
                  </treecols>
                
                  <treechildren>
                    <treeitem>
                      <treerow>
                        <treecell label="[e-mail]"/>
                        <treecell label="Top secret plans"/>
                      </treerow>
                    </treeitem>
                    <treeitem>
                      <treerow>
                        <treecell label="[e-mail]"/>
                        <treecell label="Top secret plans"/>
                      </treerow>
                    </treeitem>
                    <treeitem>
                      <treerow>
                        <treecell label="[e-mail]"/>
                        <treecell label="Top secret plans"/>
                      </treerow>
                    </treeitem>

I tried to track down a dupe for this, but did not succeed. WFM on Windows and Linux; reopen if you can reproduce in the latest builds.
