I guess you second case is not related to the innerHtml call. If yes please open a new issue for this.

In real browser, when I add the inner html of one div A to another div B, the height of B is also added by the height of A. But in htmlunit, it doesn't. The test code to reproduce:
~~~
    public static void testDivAdd() throws Exception
    {
        List<String> alerts = new ArrayList<>();
        WebClient wc=new WebClient();
        wc.setAlertHandler(new CollectingAlertHandler(alerts));
        wc.getPage(HtmlUnitTest.class.getResource("divadd.html"));
        System.out.println(alerts.toString());
    }
~~~
The content of the divadd.html:
~~~
<html>
<head>
    <title>test</title>
</head>

<body>
<div id="div1" style="height: 18px">
    aaa<br/>
</div>
<div id="templayer" ></div>

<script language="JavaScript">
function init(){ 
    templayer.innerHTML=""; 
    alert("before "+templayer.offsetHeight);
    templayer.innerHTML+=div1.innerHTML; 
    alert("after "+templayer.offsetHeight);
}
document.body.onload=init;
</script>
</body>
</html>
~~~
