"selected" attribute for <option> tag is broken in r502

[pkou@…]

When HTML is created using genshi.builder.tag, then the attribute selected="selected" is not set properly for tags `<select><option selected="?" /></select>

The builder adds the attribute selected="selected" for all options regardless if they have been set as selected or not in original source code.

I believe that code in Trac is wrong: to strip out the attribute, the value needs to be None, not an empty string.

Replying to cmlenz:

It is correct. Replacing "" with None fixes the problem. Thank you for the notice.

Okay, so I'm closing this as invalid.
