When using with zoom plugin, clip: true affect the labels on the edge

[helloint]

See this demo: https://codesandbox.io/s/chart-js-data-labels-plugin-clip-issue-mqkrgd?file=/src/App.tsx It use zoom and datalabels

When using with zoom, you have to set clip: true on datalabels, otherwise the label will overlap with the yAxis

But if did this, the first and the last bar label get cut.

Because it is beyond the chart area.

The document tells me the clip is calling CanvasRenderingContext2D.clip(), so I then took a look at the source code here:

    if (model.clip) {
      area = model.area;
      ctx.beginPath();
      ctx.rect(
        area.left,
        area.top,
        area.right - area.left,
        area.bottom - area.top);
      ctx.clip();
    }

I guess maybe we can allow a paddingOffset to slightly extend the rect area, to let customer to adjust? like:

    var paddingOffset = modal.paddingOffset;
    if (model.clip) {
        area = model.area;
        ctx.beginPath();
        ctx.rect(
            area.left - paddingOffset,
            area.top - paddingOffset,
            area.right + paddingOffset * 2 - area.left,
            area.bottom + paddingOffset * 2 - area.top);
        ctx.clip();
    }
