I don't think this is a bug. If I understand the code correctly, the
lighter disappears because the minor mode is turned off when the text
scale is 0; see this line in `text-scale-increase':
(text-scale-mode (if (zerop text-scale-mode-amount) -1 1))
I also don't see anywhere in face-remap.el that specifies the lighter is
"+0" when the text scale is 0 (the default value of
`text-scale-mode-lighter' is "+0", but changes as soon as
text-scale-mode is enabled).
