Hello.

Test machine:
CentOS @ Linux 2.6.32-042stab123.2; nginx; PHP 7.2.10 with Xdebug v2.6.1

Custom formatter:

$formatter = new lessc_formatter_compressed;
$formatter->close = "}\n";

$less = new lessc();
$less->setFormatter($formatter);
$content = $less->compileFile('test.less');

Problem:
Breaks formatting after processing background SVG with animation.
