Ok, with this file I can reproduce for some reason.
It is weird because the structure is the same in the XML:

<text:a xlink:href="<a href="https://my.bluehost.com/hosting/help/713">https://my.bluehost.com/hosting/help/713</a>"
xlink:type="simple">What&apos;s this?</text:a>
<text:a
xlink:href="<a href="http://bugs.documentfoundation.org/attachment.cgi?id=138358">http://bugs.documentfoundation.org/attachment.cgi?id=138358</a>"
xlink:type="simple"><span class=""><a href="http://bugs.documentfoundation.org/attachment.cgi?id=138358" name="attach_138358" title="side by side samples of both delete methods">attachment 138358</a> <a href="http://bugs.documentfoundation.org/attachment.cgi?id=138358&action=edit" title="side by side samples of both delete methods">[details]</a></span></text:a>

Yet my copied attachment link does not behave like that with backspace.
