Not sure how these tests worked before. PopoverModule was not added in the shallow test. So the popover content could never get projected.

Also, triggerEventHandler doesn't provide a {root: true} option. Since the search box would be outside the host element's scope, this trigger call just doesn't work.

That's how - it wasn't using the real popover (so those tags are basically ignored), which your test is now. So only the searchbox was mocked as an actual component - but it was never projected. That's also why the root wasn't there before.

You also might be able to use read: DebugElement to trigger the event handler since you can't use a selector directly in there.
