Test Word file

As in the title, when content is copied from MS Word and then pasted inside browser, clipboard data transfer `text/html` content has some of the spaces removed.

For example:

Having a Word file (attached) with simple italic text, which can be represented like:

<i>Italic</i> text.

When copied, the `html/text` content is represented in a system clipboard with:

<p class=MsoNormal>
    <i style='mso-bidi-font-style:normal'>
        <span style='mso-ansi-language:PL'>Italic</span>
    </i>
    <span style='mso-ansi-language:PL'> text.<o:p></o:p></span>
</p>

But when pasted to Safari and accessed on `paste` event via `evt.clipboardData.getData( 'text/html' )` it is returned as:

<p class="MsoNormal" style="margin: 0cm 0cm 8pt...">
    <i>
        <span>Italic</span>
    </i>
    <span>text.<o:p></o:p></span>
</p>

When you can see the space is clearly missing.

It works fine on both Chrome and Firefox. Can be easily reproduced on this codepen - https://codepen.io/f1ames/pen/QBVZyM.

Safari version 11.1.2 (13605.3.8).
Microsoft Word version - 16.17 (180909).
