Embedding this on a page makes page scroll to this

[hauswirth]

Pages that embed the read-only expression tree component seem to auto-scroll to make that component shown.

For example, when you click on this link, you won't see the top of the page, but it will scroll down so that the embedded read-only expression tree is fully visible:

This may be convenient in some cases, but in most cases (like the various progmiscon pages) it's problematic.
