If an instant preview inset is wrapped around something that produces

Is this related to: http://www.lyx.org/trac/ticket/8636 ?

Yes. Thanks for pointing me to this ticket Liviu, which is essentially the
same problem as http://www.lyx.org/trac/ticket/7522, although from a quick
scan neither ticket makes any mention of possible malicious use of this
"feature", as suggested below. A \gobble command really does "eat" into the
pdf, and with more elaborate coding could do real damage while being
invisible in the LyX document.
I agree this is a problem. It seems to me that if we have problems
compiling, then we should simply fail and not try to display a preview
image. Of course, that does not deal with the invisible image. I don't know
what to do there other than to test its size and, again, refuse to display
the preview if it is too small.

It is then adviced to make the background of the previews slightly
different than the background of the text area.
For the empty images (with size 0x0), we should indeed paint something
else (on my long, long todo list).

I'm not a developer and so have no idea of the feasibility of this. I
wonder if it is possible to have alternative views of a preview inset?
One would be the current one, trying to give a faithful rendering of the
inset's contents; the other would be in the style of Note insets with a
label and different background. Even for empty insets the label would be
there to alert the reader, so there would be no need for code to test
the inset's contents. The views would be switched from the View menu as
Open/Close All Insets does now. Normally one wouldn't bother with the
labelled view, except for a LyX document received from elsewhere and
opened for the first time.
