AliReza 0e56d9c8aa math in Persian text: lists read right-to-left, every content text goes through MathText, chat input picks its direction per line
Measured by rendering every question, option and several tutor answers in
Chrome and comparing the on-screen x of each number (2026-09-29):
- A list inside a sentence ('از −۳ به −۲، −۱، ۰ می‌رسیم', 'الگویِ ۲، ۵، ۸')
  was locked as one left-to-right run, so all 482 read backwards. '،' and
  '؛' outside brackets now split the run; sets and coordinates in brackets
  stay one run. Locked runs are isolates (isolate-override), otherwise the
  comma between two of them was still pulled left-to-right.
- Without MathText 704 of 931 minus signs and 602 of 983 expressions were
  misplaced; lesson and island titles, the lesson intro, unit blurb,
  notification bodies and ticket messages now go through it.
- The chat box takes its direction from each line's first letter, so a
  line of pure math stays left-to-right while typing. A line that starts
  in Persian can still show its math reordered inside the box; a textarea
  cannot isolate part of its text. The sent message renders correctly.

Four expressions with Persian words inside them ('f(x) = (ریشه دوم x) + ۵۰')
remain ambiguous.
