Subject: Inherit outer font in text-in-math environments
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=d72b9b0238bd33197f0cea4a36d90d78d1cbc666;p=features.git

Inherit outer font in text-in-math environments

The text-in-math environments such as \text, \mbox, \fbox, \makebox
and so on, inherit the outer text font. This commit reflects this
in the on-screen representation.

Fixes #12950.
