This CL does more than commit description as follows:
1) It propagates new information to the browser process.
2) We check the value to fix clipboard case.

Could you file a dependent crbug and update your description?

I thought the description is clear enough but I will update this.
This is not regression. It is already fixed and there is already a corresponding
crbug: https://bugs.chromium.org/p/chromium/issues/detail?id=12392
Actually, the fix for this issue suppresses all non-user initated selection
events that I would like to add back.

     // Set the CLIPBOARD_TYPE_SELECTION to the ui::Clipboard.
     ui::ScopedClipboardWriter clipboard_writer(ui::CLIPBOARD_TYPE_SELECTION);
     clipboard_writer.WriteText(selection->selected_text());
