Proposal

Please re-state the problem that we are trying to solve in this issue.

Chat - The first option in Notifications preference is always highlighted

What is the root cause of that problem?

The problem is related to the BaseSelectionList component, there is an useEffect that resets the focus and scrolls to the first section when there is at least one section in the sections array.

App/src/components/SelectionList/BaseSelectionList.js

Lines 340 to 351 in dee9b31

	useEffect(() => {
	// do not change focus on the first render, as it should focus on the selected item
	if (firstLayoutRef.current) {
	return;
	}
	// set the focus on the first item when the sections list is changed
	if (sections.length > 0) {
	updateAndScrollToFocusedIndex(0);
	}
	// eslint-disable-next-line react-hooks/exhaustive-deps
	}, [sections]);

The code above came through this PR #30438 related to the issue above #29080

What changes do you think we should make in order to solve the problem?

We should change this useEffect to only resets the focus and scroll to the first section when there is at least one section in the sections array and there are no selected sections.

For example,

function shouldUpdateFocusedSection(sections) {
    const availableSections = lodashGet(sections, '[0].data', []);

    return _.all(availableSections, (section) => !section.isSelected);
}

function BaseSelectionList({
  ...

    useEffect(() => {
        // do not change focus on the first render, as it should focus on the selected item
        if (firstLayoutRef.current) {
            return;
        }

        // set the focus on the first item when the sections list is changed
        if (shouldUpdateFocusedSection(sections)) {
            updateAndScrollToFocusedIndex(0);
        }
        // eslint-disable-next-line react-hooks/exhaustive-deps
    }, [sections]);

    ...
});

What alternative solutions did you explore? (Optional)

The main branch already has the code with the solution from the issue above #29080, but the problem still occurring.

That's why I created this proposal.

Proposal

Please re-state the problem that we are trying to solve in this issue.

The first option in Notifications preference is always highlighted

What is the root cause of that problem?

We change focusedIndex and scroll to the first option whenever the sections are changed. It doesn't make sense because it can be changed when the search value isn't changed.

App/src/components/SelectionList/BaseSelectionList.js

Line 349 in 5df95a1

if (sections.length > 0) {

What changes do you think we should make in order to solve the problem?

We should only scroll to the first option when both textInputValue and sections are changed.
