[HTTPS-Everywhere] Possible problem with "src" URLs in <embed> tags

[mezzanine at Safe-mail.net]

The following may be worth looking into. When the src attribute of an
<embed> tag references a URL, it appears that the URL is _not_
processed by the HTTPS-Everywhere extension. For instance, a URL
might be referenced in a manner similar to the following:

<embed src="http://www.example.org/content"></embed>


(From what one remembers, this issue showed up with the "release"
version of the extension, as opposed to the "development" version.)
