issue with link in label

Hi all,

I am doing a sankey plot and I'd like each of my nodes to have a label that can be clickable and redirects to some link.

fig = go.Figure( 
        data=[
            go.Sankey(
                arrangement='fixed',
                node=dict(label=labels, color=label_colors),
                link=dict(
                    source=links["source"],
                    target=links["target"],
                    value=links["value"],
                    color=links["link_c"],
                ),
            )
        ]
    )

However, when exporting the plotly file to html, the link tag appears but the href doesnt, but when further inspecting it appears in "data-unformatted" part of the code below:

<text class="node-label" style="cursor: default; font-family: Helvetica; font-size: 12px; fill: rgb(42, 63, 95); fill-opacity: 1; white-space: pre; pointer-events: all; text-shadow: white 1px 1px 1px, white -1px -1px 1px, white 1px -1px 1px, white -1px 1px 1px;" data-notex="1" data-unformatted="<a href='google.com'>test</a>" data-math="N" x="0" y="0" text-anchor="start" transform="translate(23.25,4.449999999999999)"><a style="cursor:pointer">test</a></text>

Is there any way I can get this to work (I'd want <a href='google.com'>test</a> instead of the <a style="cursor:pointer">test</a>)

Thanks!

Start from Sankey node-label rendering and the exported HTML/SVG markup shown in the issue. Investigate why the href is removed while the label text remains, then verify that exported node labels retain working links without changing ordinary label rendering.
