Hello:
I guess this is a bug:
When I write text with non-default font size (eg. small) and insert within this
text subscript or superscript characters afterwards, lyx applies the same font
size to the subscript/superscript characters as the surrounding font's size
(that is small). The subscript/superscript font should be proportionally
smaller than the surrounding font. In the source it is visible that lyx applies
the font size command to the subscript/superscript text:
{\small{subscript A\textsubscript{{\small{2}}} bug}}{\small \par}
The font size command should not be applied to the subscript text as
\textsubscript takes care of the font size. The same regards to superscript.
This occurs in lyx 2.0.6.
