Commented Unassigned: Shape of the comment box changes to a giant Curved Arrow [14045]

As mentioned in some java posts, comment boxes are changing shape by themselves when saving XLSX.
Here is one bugzilla link:

So, are there any fixes already for NPOI in C# for this problem?

Thanks in advance
David
