Created attachment 159663 [details] Screenshot For example on http://brmullikin.com/classical_texts/greek/aeschines/against_ctesiphon (screenshot attached), the A of the first "Aeschines" and the J of "Jump to paragraph" should be the same size as the subsequent word, since they have ::first-letter { font-size: 1em; }, but they get treated separately and fail to get autosized.

Comment on attachment 159756 [details] Patch ignore wrong bug.
Do you know if the site has been changed? While I can't reproduce the problem here, the page itself doesn't look identical to the screenshot anymore.
Marking this bug Resolved WontFix because the TEXT_AUTOSIZING feature was removed in <https://trac.webkit.org/changeset/206119> (bug #162167). See bug 84186, comment 32 for more details.
