Hello all,
I've got a report on a strange behaviour of textstyle-update in LyX 2.4.0.
If I select a character (say a) in math equation, then execute
textstyle-update color 3
in LyX 2.3 is simply turned the character into blue, and in th LaTeX
source I see
{\color{blue}a} as expected, but with LyX 2.4.0 the character is also
turning upright instead
of staying italic, and the LaTeX source shows
{\color{blue}{\normalsize \mathrm{\mathrm{\mathrm{a}}}}}
which is probably undesired.
To me, it looks like the text in equations does not update any parameters
of the current font.
The changes in the LaTeX source can be explained by 58103cf, but this
commit is not the fault, it just worsen the symptoms.
You can see that in LyX 2.3 with colors, as this is a parameter math knew
about then.
If I create a blue character then select it and execute textstyle-update
series bold,
the character is turned black and the LaTeX source has an undesired
\normalcolor.
Should the font parameters be tracked in equations? I would expect the
default shape
would be italic in an equation.
Another problem with 58103cf is that \mathrm does not only change the font
family, but
the shape as well, so I'm not sure it should be used as it is being used
now...
Somewhat but not entirely related to that, if I execute textstyle-update
shape up, LyX crash and I get a segmentation fault in 2.3.7, and "Exception:
basic_string::_M_construct null not valid" on LyX 2.4 and master.
