I added the following text:

If a transform function causes the CTM of an object to be non-invertible, the
object and it's content does not get displayed.

EXAMPLE:
The object in the following example gets scaled by 0.

<style>
.box {
    transform: scale(0);
}
</style>

<div class="box">
    Not visible
</div>
The scaling causes a non-invertible CTM for the coordinate space of the div
box. Therefore neither the div box, nor the text in it get displayed.


Anything that should be changed? Can we close the bug?
