use .html instead of .text ?

Could include <tspan>'s for styling - side effects/downsides?

Might break on safari:

SVG elements and other non-HTML elements do not support the innerHTML property, and thus are incompatible with selection.html. Consider using XMLSerializer to convert a DOM subtree to text. See also the innersvg polyfill, which provides a shim to support the innerHTML property on SVG elements.
