It still fails for \textdegree:

- \textdegree in math-mode input as-is
- \textdegree in "mathematical text" wrapped in \ensuremath{}

Both, textsymbols and mathsymbols are colored in "math" color.

Unit symbols wrong when using a fraction in \text:

\begin_inset Formula $50\,\text{\frac{m}{s}}$
\end_inset

exported as

$50\,\text{\ensuremath{\frac{m}{s}}}$

(upright in the GUI but italic in the output).

It works fine with \mathrm:

Fraction units with mathrm:
\begin_inset Formula $50\,\mathrm{\frac{m}{s}}$
\end_inset

(upright in the GUI and in the output).
