The problem is that many authors use "transparent" or "opaque", because they
do not want the object to hide other elements on the page (i.e. drop down

I believe this is normal behavior as this alternative text is provided for
UAs that do not support the element wrapping that text. 

I came up with a technique that allows dynamic resizing of videos. This
means that if the container is set in EMs, the video can increase/decrease
its size (keeping the same aspect ratio) in relation to the user's text-size
settings. That same technique can hide content behind the object which -
unlike - alternative content is *accessible* to screen-readers (as it is
outside of the objects tags):

This method prevents all possible issues related to the edges outside of the
content box (margin, border, and padding):
