Steps to reproduce
- Open s:pt:Page:Elementos de Arithmetica.djvu/302 in edit mode
- Replace the attribute {| width=100% by the CSS equivalent {| style="width: 100%;"
- Save the page
Actual result
The line breaks before the code |- disappear, breaking the table syntax.
Expected result
Only the first line is changed, and the table syntax is still correct.
I tested with Firefox, with JavaScript enabled, and was unable to revert to the working version.
