CSS page jumps lines to the top on save

This was a problem a year or 2 ago and was fixed but has reappeared.

When saving my style.css file after edits the screen jumps up and it loses focus on where I was working.

This happens when prettify is switched on on save of css and this code is on the page:

.l-bg-purple {
background: -webkit-gradient(
linear,
left top,
right top,
from(#65365e),
to(#70758c)
) !important;
background: -webkit-gradient(linear, left top, right top, from(#65365e), to(#70758c)) !important;
background: linear-gradient(to right, #65365e, #70758c) !important;
color: #fff;
}

This part is duplicated on each and every save:

background: -webkit-gradient(
linear,
left top,
right top,
from(#65365e),
to(#70758c)
) !important;
