Transparent text when sharing Matrix and AlphaImageLoader filters in IE

I came across an interesting IE bug (when it was superimposed on a block), with a background from a png image with an alpha channel, an AlphaImageLoader and some other DX filter, the contents of the block become a kind of mask.



Initially, my goal was to rotate such a block, in IE for this I decided to use the Matrix filter. But I ran into a glitch in which the png flies the alpha channel (as I understood this glitch manifests itself not only with Matrix but with other filters, here it has already been described ) if not assigned to background-color.
')
The decision drew here .

But the result was like this - www.dinkypage.com/62781

The thing is interesting, but I would love to get rid of it now, though I don’t know how ...
