In a paper I recently wrote I noticed some ugly zigzag alignment on the=20
left margin of one paragraph (set with Libertinus) where a couple of=20
book titles appeared at the start of the second and fourth lines. The=20
following example demonstrates the issue.

    \definefontfeature [default]
     =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=

=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 [protrusion=3Dquality,expansion=3D=
quality]
    \setupalign=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 [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=20
possibly other characters? I know it is a small issue, but once seen it=20
is hard to un-see.
