If I copy the rendering of a simple html table, with the style sheet in the head, from Firefox and paste it in say Thunderbird (in a message in html mode), the table is copied, but not the style, for example borders are not collapsed.
If I do the same from Chromium to Thunderbird, from the same html file, styling is copied as well.
Is this expected behaviour, is there some good reasons for this? Or a bug?
I can add the html file, screenshots etc… here, or create an issue on bugzilla.
