Bug: Firefox ignores AW.Formats.String in edit mode?

Set the grid to:

setCellFormat(new AW.Formats.String);

Now if I SetCellData with HTML characters they display correctly, both in IE and Firefox.

But.

If I enter edit mode the inserted data is displayed with HTML encoding symbols in Firefox but still displayed correctly in IE.

Bug?

Yes, this is a bug - FF does not support contentEditable, so instead <input> tag is used.
