Annother interesting table one, tr/td/th outside of a <table> will never appear in the DOM. You can make up your own tags and they appear anywhere, but those three are magic and can only exist inside a table.

Forms are also weird, if you leave off the closing tag, an implicit one is included in the DOM. However, if you have inputs further down the page, and technically outside the form, they are included in the submitted form data.

(Don’t ask how I discovered that…)

Also fun stuff like you can't have a form inside a form, but if you stick a form inside a form inside a form you end up with a form in a form in the DOM anyways back when I ran into this last.
