Textfield text invisible and unable to save after pdf is generated in Ubuntu

[git-hariyali]

Bug

I am using jsPDf - 1.5.3

here is sample code
var listbox = new TextField();
listbox.edit = true;
//listbox.fieldName = "ListBox";
listbox.fontSize = 12;
listbox.multiline = true;
listbox.maxFontSize = 12;
listbox.Rect = [40, posY, 500, 120];
listbox.value = 'value';
//listbox.DA = null; // tried this after reading one story here but this didn't work
doc.addField(listbox);

This is working fine in Mac/Windows - able to edit and save PDF but not in Ubuntu environment.
In ubuntu text after the edit is not saved.
