bug#69463: 29.2; Isearch help icon has inconsistent size

[Sergio Callegari <sergio.callegari@gmail.com>]

With the hope to help others, I have managed working around the issue.
This involves going through Options->Customize Emacs->Options Matching
and then entering `x-gtk` in the modeline. In the customization buffer 
that opens, search for X Gtk Stock Map and then for 'help-browser'. 
Substitute 'help-contents' for it in "Named". Then save state so that it 
is used in the following sessions too.

Apparently, there is a lack of coordination on how icons should work 
between the breeze developers and the gnome/gtk community regarding who 
should be in charge of sizing the "scalable" icons to the correct size 
and how to pass hints about this.

My understanding is that breeze developers do not think that this is a 
bug on their side and that emacs should care of displaying the icons at 
an appropriate size.
