bad sequence header length while parsing ffmpeg's yuv4mpegpipe

Hello.

I've upgrading from ffmpeg-4.3.2 to ffmpeg-4.4 and discovered that new ffmpeg have started to add "XCOLORRANGE=LIMITED" at end of header. So the header looks like

YUV4MPEG2 W1280 H720 F30:1 Ip A1:1 C420mpeg2 XYSCSS=420MPEG2 XCOLORRANGE=LIMITED FRAME

and x264.exe now fails with

x264-r3053-c347e7a.exe --demuxer y4m --input-fmt yuv4mpegpipe --muxer mp4 --qp 0 --output R:\out.mp4 R:\1111
y4m [error]: bad sequence header length
x264 [error]: could not open input file `R:\1111'
mp4 [error]: failed to finish movie.

I searched that MAX_YUV4_HEADER define in https://code.videolan.org/videolan/x264/-/blob/master/input/y4m.c is limited to 80 symbols

input video is obtained via:
