Header pattern disappeared

Hello,

I just upgraded to 4.3.4 from 4.3.3 and I noticed that the header pattern disappeared. It appears that it’s only linked to the admin-ajax.css file (which gets loaded even in non-admin pages, btw):

.header, .footer {
    background-image: url("pattern_8.png");
}

Quick’n’ dirty fix for those also affected by that same issue (place it in the custom CSS box / style.css / child theme css depending on your setup):

/* 4.3.4 bugfix - force pattern loading */
.header, .footer {
    background-image: url(../evolve/library/media/images/pattern/pattern_8.png) !important;
}
