I am using EPPlus 4.0.4 thru Nuget using VS 2013. I'm setting the visible property to false on an ExcelComment and upon opening my Excel document there is my comment clearly seen plain as day. I've inspected the vml for the drawing and the visibility property says 'hidde' instead of 'hidden'. Once I click and enter the cell, Excel fixes this for me and the visibility property says 'hidden' properly. Can someone look into fixing this for the EPPlus release on Nuget?
Here is a snippet of the vml portion that is inaccurate:
```
<v:shape id="vml1" type="#_x0000_t202" style="position:absolute;z-index:1; visibility:hidde" fillcolor="#FFFFE0" o:insetmode="auto" strokeweight="1pt">
```
