Build ID: 2002081922

I have this javascript code in my html page:
<SCRIPT>
<span onclick="var select_element = 
document.getElementsByName("texts.rubrics_0)[0];
var size_element = document.getElementsByName("size_texts.rubrics_0")[0];
var span_element = document.getElementsByName("expand_button_texts.rubrics_0")[0];
var text = span_element.childNodes[0];
var new_text;
if (size_element.value == 0) {
	size_element.value = select_element.size;
	select_element.size = select_element.length;
	new_text = document.createTextNode("Sbalit");

} else {
	select_element.size = size_element.value;
	size_element.value = 0;
	new_text = document.createTextNode("Rozbalit");
}
span_element.replaceChild(new_text,text); class="urs-link"
name="expand_button_texts.rubrics_0">Rozbalit</span>
</SCRIPT>
where "texts.rubrics_0" is name of a select box. After click on the span, it
resizes and increases it's height. After another click, it resizes back to
original height, but the scrollbar's height remains on the height after the
first resize.

In my opinion, the scrollbar should resize to it's original height.

I include some screenshots...

Thanks

<SCRIPT></SCRIPT> mark's aren't in the original code. It is a mistake.

CC'ing [e-mail] - this bug is close to HTML Form Controls component.

Please check your Javascript code.
If it is as you posted here it seems that your 
onClick code is
onclick="var select_element = 
document.getElementsByName("

The rest of it is probably ignored.

Try to move your code in a function.

See any errors in Javascript Console.

Adam is right; this is not JS Engine; sending to HTML Form Controls.
Roman: thank you for such a well-written report!!!
