Well, looks like I found the problem, maybe, and fixed it, maybe. Looks like there is a breaking change, indeed, added
<bdi dir="ltr/rtl"></bdi>
on each line. But I'm still not sure I'm not wrong, so I really help somebody will know what exactly happened this week, where and how, so I'll be sure I fixed it right, and everywhere it was needed. I didn't find any relevant task on Phsbricator
with this change.
