Is it necessary to include this comment in the source of Sybil's page. It seems to be the reason the page cannot be edited visually.

Technically, a bug is something that does not work the way it is supposed to, a limitation is a feature that has yet to been implemented. The error message and other references state that visual editing is not supported for complex code, thus it is doing what was intended, even if incomplete.
BTW, I had the privilege of meeting the bug lady herself, Grace Hopper, many years ago.
Regardless of that, I'd still advice all users to use source mode - visual editor has too many problems with it to make it worthwhile using for anything other than very simple edits in my opinion.
The problem is that there are a couple of things which apparently cannot be edited textually (correct me if I am wrong). The incident starting this was the inability to change the sort order of the new category "medical personnel" for Sybil's page without the visual editor.
There was a time when comment worked in the Visual Editor (I remember it). They had an icon like the puzzle piece, but for comments. So this isn't a feature yet to be implemented, but something broken and then called a "limitation".
I've created a thread on Community Central to ask about this lameness: HTML comments break the current Visual Editor? So far no one has commented.
I can edit categories in source mode, can't you?
Not that I see. In the source text you mean? I even did a text search for "medical" in the source for Sybil's page and got no hits. I do see the corresponding textual diffs in the history, but cannot find it in the source. Do you see it if you edit anonymously?
True, embedded comments were not specifically called out as advanced features like nested templates, for example.
If you look at the modules to the right of the edit window then the "Categories" module should still be there - if you've expanded the edit window so that it's the full width of the screen you can decrease it again by clicking on the little left pointing triangle in the thin bar to the right of the window.
Interesting, it looks to be the Chrome browser, or perhaps the way I have it configured. I am using a few plugins, like "https anywhere". When I go to text mode in Chrome, everything on the right dissapears. If I do the same thing in Firefox or Opera, the things on the right remain. I am currently on Linux so I cannot test IE at the moment.
I'm glad that's that mystery solved!
What do you think?
