I think this issue wasn't really solved by the fix, and the bug persists.
you think ? can you please be more specific?
I also think a "embed-inline-center" might me missing, because if you select an image with centered alignment or no alignment at all, the line will be broken and the image will be treated line a block object and stop being inline.
No! You can not (through the GUI) select center and inline at the same time anymore so embed-inline-center is not needed. And by the way, how would a centered inline image be rendered ?
Without alignment, this gives something like the added screenshot, ie the image is inline and has the default browser style.
