And deliver the value to the top content pres context, but it's not used in this commit. The value will be used in the next commit. One caveat is that areas covered by the dynamic toolbar will be outside of the content area, which means implementers of GeckoView needs to call setVerticalClipping with _negative_ values. Depends on D50416 Differential Revision: https://phabricator.services.mozilla.com/D50417 --HG-- extra : moz-landing-system : lando
