Description of the feature
Illustrations

Device: nexus 5
Channel: Morph Browser
Build: OTA-15

Steps to reproduce

When I go on some website like journalism of France (Mediapart), I can't share media or pics, or movie, because when I comment the news, or blog, when I go to add media, it opened an new tab or window, for select my media (pics, or youtube movie for example (insert link)); and, when I click on add in the new tab for the old tab with the comment section, the new tab for insert media don't work, I can't close the window for finish the insert pics, so I can't insert the media in my comment, maybe it's an javascript problem, or I don't know.

Actual behavior

Logfiles and additional information

i think this is similar to the behaviour when using social logins, where on the desktop it's open a new window, log in, close and the original window picks it up. on morph it opens a new window and stays there
an concrete example would be a google login on https://udemy.com for example
