AX: setting the selected children of a list box deselects and reselects
options that stay selected
https://bugs.webkit.org/show_bug.cgi?id=327388
rdar://189899129
Reviewed by Tyler Wilcock.
AccessibilityNodeObject::setSelectedChildren() first deselected every selected
option and then
selected the requested ones. When an AX user added an option to the selection
of a multi-select
list box, the options that stayed selected were therefore also deselected and
reselected, each with
input and change events. The page saw three selection changes, one of them
leaving nothing
selected, where a non-AX user selecting the option causes one.
Only deselect the options that are not among the requested ones. Selecting an
option that is
already selected does nothing.
