Error while selecting tspan

svg.js@^2.7.1
svg.select.js@^3.0.1

Are there any ways to select the tspan element?

TypeError: this.parent.group is not a function. (In 'this.parent.group()', 'this.parent.group' is undefined)

Here is the jsfiddle: https://jsfiddle.net/j4yg798x/3/

Wait for 5s for unselecting the text and selecting the tspan inside this text and check console in devtools
