View PDF Macro breaks SSL

Expected Behavior:

When viewing a page in Confluence that is SSL'ed, the content should be fully encrypted, see the URL of the screenshot below:

Observed Behavior

A page that contains the View PDF Macro will break the SSL encryption for the whole content.

Cause

When the View PDF Macro is attached, there is an extra "Get Acrobat Reader" image that is loaded, that is not fetched via SSL (http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif , instead of https://www.adobe.com/images/shared/download_buttons/get_flash_player.gif):

Even after installing Adobe Acrobat Reader, although the image disappears from the page, the image is apparently, still loaded (as observed in firebug), hence the issue:

The same behavior is not exhibited in View Word macro / View PPT Macro / View Excel Macro.
