Time: Find a better solution from scrollIntoView

[svanherk]

@dbatiste: Normally I think the actual opener (the element the user will click or focus on) should have d2l-dropdown-opener class. This class is how the dropdown logic locates the focusable opener. The d2l-dropdown-opener-behavior has some logic that I think expects this, for instance to apply focus to the opener when the use hits [Escape] inside the dropdown content. There's likely a couple more little things like that. So in this case, I think it should be on the input, but perhaps there is a reason it's not in this case?

Seems like this is not setup as Dave B suggests due to the ScrollIntoView requirements.
