51758cfc9b
Same rg + sed shenanigans as the first patch. There were two that could fail, both due to OOM: * HTMLInputElement::AfterSetAttr: If we fail (only in the type=range case) we end up with an old value without it being clamped by min/max/step. * HTMLBodyElement::AfterSetAttr: If we fail we won't peek up the DocShell's frame margins and styling could be incorrect. That seems better than having to deal with broken states after we've already set the attribute. Depends on D176069 Differential Revision: https://phabricator.services.mozilla.com/D176070
