Per Bug1248708 comment 81, on linux platform, looks like the SVG stroke is respecting a mitre limit at the join, whereas the stroking of the HTML text doesn't have that feature and so the sharp angle becomes a long point. The comparison for stroking HTML text vs. SVG text can be referred in . This is a question worth investigating. Is our behavior consistent across platforms for a given glyph shape? (Does it depend on the gfx backend being used, skia vs cairo?) And can we make the HTML glyph-stroking respect a mitre limit?  https://treeherder.mozilla.org/#/jobs?repo=try&revision=d47e85f2596e
