(I'm going through old bug reports that have unfortunately gotten no
responses yet.)

I'm not quite sure I understand the bug report, but I tried this recipe,
and I'm not able to reproduce any odd behaviour here in Emacs 27 (I
think).

If I type

l M-x insert-char RET 336 RET

I get

l̶

which is displayed here as an l with a dash after it -- no overstrikes
or anything.  The same happens with a space character instead of an l.

I'm guessing something has changed with combining characters here?  Or
do I need to be in a particular language environment for the l and the
dash to combine?
