Hello,

I have found a strange typesetting effect in TeXmacs. When I try to add a
color to a superscript symbol, it will make the subscript symbol's position
move down a little bit.

An screenshot of this problem is like this:

in which I added two grey horizontal lines for easily reading the position
difference.

The math code (in plain text) is like this:
l<rsub|\<ast\>><rsup|<with|color|blue|\<bullet\>>>l<rsub|\<ast\>><rsup|\<ast
\>>,l<rsub|\<ast\>><rsup|\<bullet\>>l<rsup|\<ast\>><rsub|\<ast\>>

(In TeXmacs display code) picture: https://flic.kr/p/r4pxPx

Is this slightly move effect a special design or maybe just a typesetting bug?

Thank you!

Best Regards,
Chen
