Hi,
We have upgraded Jquery from 1.5.1 to 3.7.0 and our project is based on Rich faces version 4.0.0
After Jquery upgrade I upgraded htmlunit from 2.17 to 3.4.0. Now after upgrade below test

    @Test
public void testServerClick() throws IOException, SAXException {
    HtmlPage page = environment.getPage("/dropDownMenu_serverMode.jsf");
    HtmlDivision item = (HtmlDivision) page.getElementById("form:saveAll");
    assertNotNull(item);
    DropDownMenuBean.setCurrent("none");
    item.click();
    item = (HtmlDivision) page.getElementById("form:saveAll");
    assertNotNull(item);
    assertEquals("action", DropDownMenuBean.getCurrent());
}

is failing with warning
WARNING: Calling click() ignored because the target element
HtmlDivision[

] is not displayed.

I verified item.isDisplayed() , it is returning false only.
I have tried page.wait or set innerheight etc., but nothing helps.

Could you please let me know how to fix this test?
