Fixed by this commit in Blink:

https://chromium.googlesource.com/chromium/src.git/+/f75cb329068c3768b2d4e6b0c0243795c81d1ae6

It might be above my expertise to merge but still looking into how to do.

I think Blink introduced 'line layout' specific to SVG sometime after split and it is not 1-1 merge.
