CSS combining not working with inline svg rgb definition

[qbadev]

Contao 3.5.28. I use inline svg inside my css. I noticed, that after combining, contao adds a quote inside rgb color definition.
My css is:

background-image: url("data:image/svg+xml;charset=utf8,<svg xmlns='http://www.w3.org/2000/svg'><path stroke='rgb(255, 255, 255)'></svg>");

after combining it looks as shown below

background-image: url("data:image/svg+xml;charset=utf8,<svg xmlns='http://www.w3.org/2000/svg'><path stroke='rgb(255, 255, 255")'></svg>");

Combiner adds needless double quote just before rgb ending bracket

What happens if you use single quotes for the image and double quotes for the attributes?

background-image: url('data:image/svg+xml;charset=utf8,<svg xmlns="http://www.w3.org/2000/svg"><path stroke="rgb(255, 255, 255)"></svg>');

It outputs sth much more weird than before, as it still adds double quote before ending bracket and also changes first single quote after url( to double quote. I think combiner "thinks" that rgb ending bracket is the end of url definition.

background-image: url("data:image/svg+xml;charset=utf8,<svg xmlns="http://www.w3.org/2000/svg"><path stroke="rgb(255, 255, 255")"></svg>');
