In a paper I recently wrote I noticed some ugly zigzag alignment on the left margin of one paragraph (set with Libertinus) where a couple of book titles appeared at the start of the second and fourth lines. The following example demonstrates the issue.

\definefontfeature [default]
                   [default]
                   [protrusion=quality,expansion=quality]
\setupalign        [hz,hanging]

\startbuffer
Here is a line of text, the first sentence in the demonstration.\\
{\em Then} the next sentence in the paragraph follows.\\
You can see that the italic {\em T} appears to be a bit indented.\\
{\em There } might be a way to shift it to the left that little bit.\\
Perhaps a protrusion setting.\\
{\em This} does appear to depend to on the font used. With Modern and\\
Libertinus it is worse, with Times a bit better.
\blank
\stopbuffer

\starttext
Modern\\
\getbuffer
Times\\
\setupbodyfont[times]
\getbuffer
Libertinus\\
\setupbodyfont[libertinus]
\getbuffer
\stoptext

How can one set a small left-margin protrusion for the italic T and possibly other characters? I know it is a small issue, but once seen it is hard to un-see.
