How can I make tooltips align vertically for vertical bar charts?

I have an issue with bar charts’ tooltip setup being horizontal in most cases. I prefer the tooltip to be above the bar, ‘pointing’ down at the bar with its caret, and if it’s coming off the screen, it should then be inside the bar, ‘pointing’ to the top of the bar.

The reason I want this is because the way it works now causes problems with stacked bar charts, like this:

I tried setting tooltips.yAlign to bottom but that seems to have problems with caret position and not adapting to cases where it comes off the screen, like so:

So… Is there a way to get a vertical tooltip on vertical bar charts that works correctly without making a fully custom tooltip implementation?

tooltips: {
    enabled: true,
    mode: 'nearest',
    displayColors: false,
    callbacks: {
        title: function () {
            return null;
        },
        label: function (tooltip) {
            // This is a variable that's irrelevant to the issue but I didn't want to exclude anything from the snippet
            return tooltip.value + (isShowingPercentages ? '%' : '');
        }
    }
}

I don’t know if this is still an issue in more recent implementations but it hasn’t been marked as resolved so…

My solution is that we have an ugly tooltip right now in production.
