First line of signature help is treated as markdown and markdown errors
(like unescaped underscore) are highlighted as errors. It looks like this .
I wondered why hover action doesn't have this problem and figured out that syntax there is explicitly set to lua using this command:
vim.cmd(string.format("syntax region %s start=+\\%%%dl+ end=+\\%%%dl+ contains=%s", name, start, finish + 1, lang)) (hover.lua#239L) where, for example, name=lua1, start=1, finish=1, lang=@LUA
If I comment this line out, the floating window looks like in the signature help case.
