toWebGL() causes heatmaply to fail to render

[doliv071]

Describe the bug

When using toWebGL to convert a heatmaply to webgl, it fails to render all but the axes and color legend

To Reproduce

hm <- heatmaply::heatmaply(matrix(rnorm(25), 5, 5))
hm |> plotly::toWebGL()

Expected behavior

it should plot something

Screenshots

Additional context

Just to see if I could figure out which portion was failing to render using webgl, I modified the type by hand and it plots just fine. Although I'm not entirely sure this is a valid way of causing it to be rendered by webgl...

for(i in 1:length(hm$x$attrs)){ 
    if(!is.null(hm$x$attrs[[i]]$type)){ 
        hm$x$attrs[[i]]$type <- paste0(hm$x$attrs[[i]]$type, "gl") 
    }
}

I appreciate this is not ideal, but plotly heatmaps have been broken in webGL for years, so I'm not inclined to look into it

eg here is a simple mtcars heatmap:
