typst formulas have a smaller font size

[cyperion]

Displayed inline Math formulas are scaled wrongly using Typst as the math format.
KaTeX Formulas have a nicely scaled font size fitting to that of the text.
Typst formulas render in a smaller, off-looking fontsize.
This is probably a bug.

System specification:

• Arch Linux
• zennotes-bin v2.45.0 via AUR
• DE: KDE Plasma

Fixed on the v2.46.0 branch in ac480df (release PR #749). Thanks for the report and the side-by-side screenshots; they were exactly right.

KaTeX draws Computer Modern at 1.21 times the text size (its own stylesheet asks for it, because the family sits small on its em square), while the Typst SVG was sized at a plain 1em. New Computer Modern shares the metrics, so the same formula came out a fifth smaller under Typst: 52 px wide against KaTeX's 63 for E = h nu at the default text size. Typst formulas now use the same 1.21 factor in both the editor and the reading view, display blocks included, so switching engines no longer changes how big the math is. The Math size setting still scales on top.

While there, the recolor that makes Typst formulas follow the theme only handled glyph fills, so a square root's bar and fraction lines (black strokes in Typst's export) stayed black on dark themes; strokes are recolored now too.

It ships with 2.46.0.
