makeImageData with Scrolling Table issue

Hi, my node template uses scrolling table. When i try to use diagram.makeImageData() with scale:1 and maxSize: new go.Size(Infinity, Infinity) some columns are missing from scrolling table node as shown in attached image. Issue with large image. For small images its working fine.

As you can see for some nodes only the first column is getting exported. For some nodes no columns (only blank table) being displayed after export.

Is this the same as Unable to download complete diagram as image ? I have answered there.
