This fixes the dictionary manager and various other places where a XUL
element was being created with createElement(), and also simplifies a lot
of createElementNS(HTML_NS, ...) calls.
This might cause some minor regressions but everything tested has
worked. Not touching preferences (#2659) or bindings.
- Widths are now correct
- Rows are a little too tall
- Field value vertical alignment is off
- Platform styling isn't done and some styles might be redundant
- Still can't scroll vertically
- Creator name inputs still displayed wrong
- Use IDs as list item values
- Use addEventListener() so events are actually received
- Put menulist inside <td>
* This causes a small appearance regression at the moment because
<td> margins/padding are a bit off, but that issue is visible on
all other fields already.
