You're welcome! To fix the underlaying issue would be great, but it i think could be really hard to find a solution which interprets all possible media queries and transforms...

Ok that sound great. 👍 Beside that, would it be possible to make a small release (e.g. v2.8.9) with the two bug fixes #1305 and #1303? In my current project...

Yes it should. So it would be nice if this got merged. Edit: It seems that in the next version ([3.0.0](https://github.com/ampproject/amp-toolbox/blob/v3.0.0-canary.2/packages/optimizer/package.json)) terser will be completely removed. :)
