Well, it just hasn't been implemented. There is no reason not to add it, 
if someone wants to do it.

To entertain my lack of imagination: What is the issue, if e.g. Pascal 
shows fold indicators, and you just don't use them?

You don't have to select them.

If you do select text, the gutter will show an additional fold (actually 
"hide") symbol, allowing you to collapse whatever text is selected.

Btw, folding may not be the best way to check for correct html nesting.
IIRC, the highlighter tries to find a matching-name closing tag, even if 
that means to skip other tags.
