`x-intersect:enter` attribute on SVG triggers `Cannot read properties of undefined (reading 'attrs')`

[Niklas Mischkulnig]

x-intersect:enter is used by Alpine.JS: https://alpinejs.dev/plugins/intersect

Error:

Uncaught TypeError: Cannot read properties of undefined (reading 'attrs')

Reproduction:

await require("htmlnano").process(
   `<svg viewBox="0 0 430 225" x-data="{shown: false}" x-intersect:enter="shown = true"></svg>`,
   {minifyJs: false, minifyCss: false}
)

Using version 2.0.2

@mrmlnc The issue has already been fixed in the master branch. However, htmlnano hasn't released any version since May.
