If line number is a multiple of 6, the tag will not show the match underline.

If line number mode 6 equals 0, click on a tag, the highlighted underline indicating match tag will not show.

I disabled all packages but the problem still produces, finally I changed to One dark syntax theme, it doesn't produce any more. So I think this is related to seti syntax theme.
