Description Chris McKenna 2013-07-31 18:02:00 UTC 
Compare the first two cells in row 1 of the table at https://en.wikipedia.org/w/index.php?title=User:Thryduulf/sandbox&oldid=566470353#Table where the Wikicode

|-
|bgcolor=""| row 1, cell 1
|bgcolor| row 1, cell 2

produces:

<tr>
<td bgcolor="">row 1, cell 1</td>
<td bgcolor="bgcolor">row 1, cell 2</td>

Row 1 cell 1 is rendered with the light grey background colour defined in the wikitable class. Row 1 cell 2 is rendered with a dark red background colour (#b00000)

The desired behaviour is that both should produce the html <td bgcolor="">
Comment 1 db [inactive,noenotif] 2013-08-03 15:48:51 UTC 
From Sanitizer::getTagAttributeCallback:

# In XHTML, attributes must have a value.
# For 'reduced' form, return explicitly the attribute name here.

Works as aspected, but it the aspected right?
Comment 2 Chris McKenna 2013-08-14 07:54:55 UTC 
That behaviour might be what is expected from the code specification, but the output it isn't what the end user expects.
Comment 3 Gabriel Wicke 2014-01-16 02:45:00 UTC 
This is causing a difference vs. Parsoid, so it would be good to fix this in PHP. See also bug 51954.
