Print in 'Current Size' when use vh instead px in the map div

[Edgar Céspedes Sabogal]

When using "vh" instead "px" in the div height, the Current mode does not work well.

In order to solution, I changed the code

domtoimage.toPng(plugin.mapContainer, {
        width: parseInt(widthForExport),
        height: parseInt(plugin.mapContainer.clientHeight)
      })
