Either option is probably fine from a web compat standpoint, but I'd

SVG WG resolution relating to this topic (minutes from Seattle 2011 F2F):
With regards to browser vendors present in that meeting, we had people
from Microsoft, Google, Mozilla and Opera.
SVG2 lists this as an issue where SVG wants to align with HTML, see
editor's draft: https://svgwg.org/svg2-draft/interact.html#SVGEvents.
