The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/de5c18194ce923fa5eeec84881ffcf96554d98f7 commit de5c18194ce923fa5eeec84881ffcf96554d98f7 Author: Rune Lillesveen <futhark@chromium.org> Date: Mon Jun 18 14:59:25 2018 Do not override kReattach for ::first-letter. We incorrectly did an override with kForce for ::first-letter recalc when we were already recalculating style for re-attachment (kReattach). This caused crashes in FirstLetterPseudoElement::DidRecalcStyle.
