Otherwise, localName is associated attribute’s local name,

Missing word "if" before localName

More detailed explanatory text, if necessary. Wrap it to about 72
characters or so. In some contexts, the first line is treated as the
subject of an email and the rest of the text as the body. The blank
line separating the summary from the body is critical (unless you omit
the body entirely); tools like rebase can get confused if you run the
two together.

Focused on the "unless you omit the body entirely" part. (Ockham's Razor)

Super amped at what I believe is my first contribution to whatwg/dom! 🎉 Long overdue.

Was a little confused about whether or not "first line in commit message" really was just the summary. Hence the duplication.

Please let me know what corrections I need to make. 💪
