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

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

Can you please help me understand the way in which it is "system dependent"?

Where are the I-search toolbar icons sought on the system? Is it emacs 
installing them or are they supposed to be system or theme provided icons?

Thanks,

Sergio Callegari
