stylefmt change SVG's letter to Uppercase

[DmitriyKurto]

I use SCSS and paste SVG on page with background-image
background-image: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' id='Layer_1' x='0px' y='0px' viewBox='0 0 35.1 35.1' style='enable-background:new 0 0 35.1 35.1%3B'%3E%3Cstyle%3E.st0%7Bfill:%2333C158%3B%7D .st1%7Bfill:url(%23SVGID_1_)%3B%7D .st2%7Bopacity:0.4%3Bfill:%23FFFFFF%3Benable-background:new %3B%7D%3C/style%3E%3Cg%3E%3Ccircle cx='17.6' cy='17.6' r='16' class='st0'/%3E%3ClinearGradient id='SVGID_1_' x1='0.5522' x2='34.5522' y1='19.7015' y2='19.7015' gradientUnits='userSpaceOnUse' gradientTransform='matrix(1 0 0 -1 0 37.2537)'%3E%3Cstop offset='0' style='stop-color:%23147F45'/%3E%3Cstop offset='1' style='stop-color:%231DBB50'/%3E%3C/linearGradient%3E%3Cpath d='M17.6 34.6c-9.4 0-17-7.6-17-17s7.6-17 17-17 17 7.6 17 17-7.7 17-17 17zm0-32.1C9.2 2.5 2.5 9.2 2.5 17.6s6.8 15.1 15.1 15.1 15.1-6.8 15.1-15.1S25.9 2.5 17.6 2.5z' class='st1'/%3E%3Cellipse cx='12.5' cy='12.5' transform='matrix(0.7071 -0.7071 0.7071 0.7071 -5.1797 12.5223)' class='st2' rx='6.8' ry='5.5'/%3E%3C/g%3E%3C/svg%3E");

SVG text includes matrix(1 0 0 -1 0 37.2537)
after runing stylefmt I get
background-image: url("data:image/svg+xml, %3Csvg xmlns='http://www.w3.org/2000/svg' id='Layer_1' x='0px' y='0px' viewBox='0 0 35.1 35.1' style='enable-background:new 0 0 35.1 35.1%3B'%3E%3Cstyle%3E.st0%7Bfill:%2333C158%3B%7D .st1%7Bfill:url(%23SVGID_1_)%3B%7D .st2%7Bopacity:0.4%3Bfill:%23FFFFFF%3Benable-background:new %3B%7D%3C/style%3E%3Cg%3E%3Ccircle cx='17.6' cy='17.6' r='16' class='st0'/%3E%3ClinearGradient id='SVGID_1_' x1='0.5522' x2='34.5522' y1='19.7015' y2='19.7015' gradientUnits='userSpaceOnUse' gradientTransform='matriX(1 0 0 -1 0 37.2537)'%3E%3Cstop offset='0' style='stop-color:%23147F45'/%3E%3Cstop offset='1' style='stop-color:%231DBB50'/%3E%3C/linearGradient%3E%3Cpath d='M17.6 34.6c-9.4 0-17-7.6-17-17s7.6-17 17-17 17 7.6 17 17-7.7 17-17 17zm0-32.1C9.2 2.5 2.5 9.2 2.5 17.6s6.8 15.1 15.1 15.1 15.1-6.8 15.1-15.1S25.9 2.5 17.6 2.5z' class='st1'/%3E%3Cellipse cx='12.5' cy='12.5' transform='matrix(0.7071 -0.7071 0.7071 0.7071 -5.1797 12.5223)' class='st2' rx='6.8' ry='5.5'/%3E%3C/g%3E%3C/svg%3E");

where matrix(1 0 0 -1 0 37.2537) becomes matriX(1 0 0 -1 0 37.2537), but matrix(0.7071 -0.7071 0.7071 0.7071 -5.1797 12.5223 don't change. Uppercase X makes error when I use webpack for building prod package.
Looks like font changes not always, because after formating in this SVG matrix is ok
