Bug 117431 – REGRESSION(r143560): Listbox select dispatches a change event by clicking its scrollbar

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Forms

[Kent Tamura]

Steps to reproduce:
1. open the following URL
data:text/html,<select name="test" id="test" multiple onchange="alert('change');"> <option value="1">Option 1</option> <option value="2">Option 2</option> <option value="3">Option 3</option> <option value="4">Option 4</option> <option value="5">Option 5</option> <option value="6">Option 6</option> <option value="7">Option 7</option> </select>
2. click on the scrollbar to show Option 5+.

Expected:
The listbox scrolls the content.

Actual:
The listbox scrolls the content, and 'change' event is dispatched even though selection state is not changed.
