Interesting edge case, nice find!

I'm not sure what the right thing to do is here, and I think the current behavior isn't too bad: The extension crashed so we don't have an extension name, but we also don't want to show an info icon on a chrome-extension URL. Overall, this seems working as intended to me.

Bisect Info:
===========

Good build : 57.0.2957.0,  Revision Range(439663)
Bad build  : 57.0.2959.0,   Revision Range(440307)

After executing the per-revision-bisect script, i got the following CL's between good and bad build versions

meacer@- Could you please look into this issue, if it's related to your change?  if not could you please help us to reassign this issue to the right owner.

Note:
------
In the good build, after loading extension, in the omnibox "i" in circle is displayed whereas in bad build, extension symbol is displayed along with its name.

The problem here is not that we're choosing the wrong icon, it's that the icon is physically misaligned in this case.  (It's too far to the left.)  Definitely not working as intended :).

Basically, the icon in question should be in the identical position, pixel-wise, when there's an extension name and when there's not; and the omnibox text should be in the same position as when we're showing the (i) icon.

Ah right, didn't notice that the icon is moving further left. I'll take a look.

The problem seems to be that IconLabelBubbleView::Layout assumes the bubble is being animated if the label is not shown. So it sets image_x to zero, moving the icon to left.

@varkha: Does this assumption still hold if the bubble just doesn't show the label and only shows the image? (asking since you are the author of https://codereview.chromium.org/1763713004/diff/160001/chrome/browser/ui/views/location_bar/icon_label_bubble_view.cc). Thanks!

What happens in the case where we're showing the (i) (i.e. there is no label)?  Why doesn't that get similarly mispositioned?

#5, if I read the current code correctly, when there is no label the icon is first allowed to slide all the way to the right and then when the right (trailing) edge of the icon is touching the trailing edge of the view the left (leading padding) starts to shrink until the view has the icon's width.

I think when you don't have a label the view is allowed to shrink all the way to the icon's width (https://cs.chromium.org/chromium/src/chrome/browser/ui/views/location_bar/icon_label_bubble_view.cc?sq=package:chromium&dr=CSs&rcl=1485202678&l=179) so the icon is taking all of the view and is put at x=0.

Able to reproduce this issue on Ubuntu 14.04 using chrome latest dev #58.0.3007.0 .
