A bug with comments within equations?

[fcanatay at gmail.com]

Greetings,

I am not sure whether what I am about to report is a bug or intended behavior. I searched on the web and couldn't find anything related. I hope this is not the wrong list to mention this. Here goes:

There seems to be a confusing behavior with imported LaTeX documents that contain comments in equations: LyX seems to render everything it finds, including the comments. Here is a minimum LaTeX source:

\documentclass{article}
\begin{document}
\[
x = y. 
% u= v.
\]
\end{document}

When imported it into Lyx, it shows on screen as
	x=y.u=v.
(see attached screenshot).

The commented part ?u=v.? seems to be inside some comment structure but there is no visible cue on the screen. The compiled pdf correctly shows only ?x=y?. However, the LyX rendering is terribly confusing, as my existing LaTeX documents look now completely different on LyX screen. 

On the other hand, if one tries to insert a comment into an equation inside LyX itself, the menu items under "Insert->Note? appear disabled in version 2.4.0~RC4. So, it is not clear to me what LyX?s stance is with respect to comments in equations.

Reporting from Mac apple silicon with LyX versions 2.4.0~RC4 and 2.3.8 under fresh install.

Cheers,
