Org may or may not do it, depending on the implementation details.
What you are seeing is because we changed the way Org is folding text to
use text properties instead of overlays (see
https://orgmode.org/Changes.html).

You may get the old behavior back by (1) Setting
`org-fold-core--optimise-for-huge-buffers' to '(grab-invisible); (2)
Setting `org-fold-core-style' to 'overlays before loading Org.

I do not consider what you report as a bug. There were ways to break Org
folding in the past (for example, by using overlays with high priority).
Actually, I am not sure why you even need to set 'invisible to nil in
your font-lock-keywords.
