I have a commercial epub that displays paragraphs with
text-indent: -1em differently between M2 and M3. M3 is truncating from the left (see first attachment), whereas M2, ADE and Calibre viewer do not truncate.
The attached
Test - ShellShock.epub demonstrates the problem (the first paragraph).
Test - ShellShock.epub
I am not sure what the correct behaviour should be? Is M3 correct and the other viewers wrong?
