Math RTL Support

This plugin fixes text direction for right-to-left[^rtl] text in math mode.

Before:

RTL text inside MathJax can render backwards:

$$ D(x) = \begin{cases} 0 & x \text{ ילנויצר} \ 1 & \text{ يقيقح ريغ} \end{cases} $$

After

$$ D(x) = \begin{cases} 0 & x \text{ רציונלי} \ 1 & \text{ غير حقيقي} \end{cases} $$

Original snippet used:

$$
D(x) = \begin{cases}
    0 & x \text{ רציונלי} \\
    1 & \text{ غير حقيقي}
    \end{cases}
$$

Settings

• RTL font style inside math: leave MathJax fonts unchanged, force serif, or use the app text font.

[^rtl]: Detected right-to-left text covers Hebrew and Arabic Unicode ranges, including Arabic supplement/extended characters and Arabic presentation forms.
