This is what I see while resizing the frame: when decreasing the width
of the frame then I-search toolbar icons get removed one by one
from the right side of the toolbar, so the toolbar never overgrows.

I don't see this life buoy on GTK.

I don't know how that breeze icon looks like.  What I see is
an icon with a blue question mark.

Thanks for the reference.  It could help anyone
who knows how to fix this bug.
