lgtm, thank you Daniel!

https://codereview.chromium.org/952443004/diff/1/content/content_browser.gypi
File content/content_browser.gypi (left):

https://codereview.chromium.org/952443004/diff/1/content/content_browser.gypi...
content/content_browser.gypi:365: 'browser/android/popup_item_type_list.h',
It looks like the following file referring to this is entirely unused as well:

content/public/android/java/src/org/chromium/content/browser/input/PopupItemType.template

I'll remove that in a follow-up.

I added the people that did the original changes. It clearly didn't scale.

But thanks for the reviews!
