overlay - featureinfo from a raster

[David0099]

Is your feature request related to a problem? Please describe. Getting problem when I try to query featureinfo from a wms-raster layer (geoserver), when using overlay as infowindow options under featureinfoOptions.

"featureinfoOptions": {
    "infowindow": "overlay"
  },

Works fine when I use infowindow or sidebar instead.

  "featureinfoOptions": {
    "infowindow": "infowindow"
  },

  "featureinfoOptions": {
    "infowindow": "sidebar"
  },

Describe the solution you'd like Is it possible to add this functionality to overlay
