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

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

I have made more tests.

The behavior that I am experiencing is due to using the breeze icon theme.

Unclear to me if the issue is in the theme itself, though. All other 
applications using this icon theme appear to be able to scale the icons 
in the theme (which I guess are svg) according to their needs.
