The prolonged implication symbol in LaTeX formulas on Wikipedia generated by the \implies keyword is graphically glitched.
See e.g. https://upload.wikimedia.org/math/1/3/e/13e30a48d35ec57948e8a577db7eb787.png from the Axiom of choice page (https://en.wikipedia.org/wiki/Axiom_of_choice).
and what's about the SVG fallback for browsers that don't fully support html5 https://en.wikipedia.org//w/index.php?title=Special:MathShowImage&hash=6254d3b551652914d929dadbbc6563c9&mode=5
Oh, I'm not sure if I understand your MathML related question well - in what concerns your screenshot, it looks good of course (I guess you did not ask about the Wikipedia page which still looks the same as pointed out in this problem description).
The same for the SVG file, looks good.
Thank you.
Year. The screenshot was actually taken from Wikipedia. But using the new rendering, that is not yet enabled for anonymous users. It can be enabled for regeistered users via the https://en.wikipedia.org/wiki/Special:Preferences#mw-prefsection-rendering and selecting MathML as Math rendering option. I I hope that it will become standard in a while.
