This is very similar to  Issue 59289 . There was a recent ish fix in

[Mac] Dismiss an open page info dialog when the location icon is clicked.

But it seems to have regressed 

My fix was only for the page info dialog (lock icon). I didn't have a chance to get to the omnibox decorations. The page info dialog correctly dismisses on a second click when it's opened.

Further clarification: my fix was for Cocoa, and I based it on what the views page info dialog implements. I assumed at the time that MacViews would *just work* since it worked in Views already - perhaps it needs some more work to get it there.

Marking available, since spqchan@ is working on other stuff right now.

I have a fix for it :)

This CL will fix the issue https://codereview.chromium.org/2720183002/
It's just taking a while to work on because my Windows laptop died. I just got my replacement so hopefully I can get to it soon

The CL has landed

Thank you for fixing this!

There seem to be issues with this with secondary-ui-md enabled. Do you know if there's a bug filed about that?

AFAIK, no
