Thanks a lot.  I checked that the problem is no longer present for me
either.

Thanks for the explanations; very useful.

Thanks once more; I spent a whole day on this :-) With non
reproducible features in the process (when using the elpa 9.5.5
version) -- sometimes the buffer was narrowed to nothing and then
widen to the buffer without only the COMMENTed headline missing;
sometimes, after the problem occurred, files with the .org extension
further visited were in Fundamental mode ...
