A fix from 4325446 introduced a rule setting
background-image
of a blank icon to none. However, the selector used for thatrule had lower specificity than another one:
.ui-button .ui-icon
which causeddashes being shown over the icons.
We needed to increase the specificity of the
.ui-icon-blank
rule past theabove selector and past
.ui-button:hover .ui-icon
. We're doing it by repeatingthe class name three times.
