[FF] Pasting content from Word causes problems

[Damian]

When pasting content from a Word document that happens to have a date field the content styles are displayed incorrectly. The height of the text is incorrect and results in excessive overlapping (see attached example).

Also, the table in the provided word document is removed.

The incorrect font styles and the removed table issue only occur in FF. IE is working well.

To reproduce:

1. Open a nightly sample
   
2. Copy the whole contents of the Test_doc_with_date.doc
   
3. Use paste from Word dialog to paste the whole contents with default settings
   

Using the same document with the date field removed fixes the style issue (see Test_doc_without_date.doc), although the table is still removed.

Pasting directly into the content area preserves the table.

The following MS-Word content which cause the problem, where the single-quote is not processed correctly by the cleaner.

<span style='mso-element:field-separator'>

[Garry Yao]

The previous fixing is incorrect, since it's the single-quote within IE conditional comments which cause the problem, double-quote is guaranteed outside.

<!--[if supportFields]>
<span style='mso-element:field-separator'>
<![endif]-->

Fixed with [3929].
