This may not be the case -- the DKIM signature uses "simple/simple" normalization, meaning that all headers are preserved wrt upper/lowercase and whitespace.

Kees, if you still have the copy that arrived straight at your chromium.org address (not via vger), you can diff it with what you get from lore to see where the culprit is. -K
