Barcode is turning dotted/dashed

[didix16]

Hi!
I'm experimenting a weird behaivour when using the border.style complex attribute.

On the document I'm setting this attribute on a span element inside a table.
Outside that table I have a barcode element wich is becoming dashed/dotted when I use the border.style="dotted" on the span element. If I remove the attribute, the barcode come back to normality.

Can it be a bug?

Thanks in advance
