Invalid Regular Expression - 3.7.0

See original GitHub issue

Just upgraded to 3.7.0 and am getting the following error:

Uncaught SyntaxError: Invalid regular expression: /^\/about\/refund(?:\/(?=$))?$/: Stack overflow
    at RegExp.exec (<anonymous>)
    at Route.match (ostrio_flow-router-extra.js?hash=96883db4695d24ad4599b4bf3f9da15a27a28f8d:3808)

The error leads to this function, with m = this.regexp.exec(decodeURIComponent(pathname)); causing the issue.

 Route.prototype.match = function(path, params) {
    var keys = this.keys,
      qsIndex = path.indexOf('?'),
      pathname = ~qsIndex ? path.slice(0, qsIndex) : path,
      m = this.regexp.exec(decodeURIComponent(pathname));

    if (!m) return false;

    for (var i = 1, len = m.length; i < len; ++i) {
      var key = keys[i - 1];
      var val = this.page._decodeURLEncodedURIComponent(m[i]);
      if (val !== undefined || !(hasOwnProperty.call(params, key.name))) {
        params[key.name] = val;
      }
    }

    return true;
  };

My route for that one looks like this:

import { FlowRouter } from 'meteor/ostrio:flow-router-extra'
FlowRouter.route('/about/refund', {
    name: 'refund',
    async action(params, queryParams) {
        const { default: Layout } = await import('/client/layout')
        const {
            default: AboutRefund
        } = await import('/imports/client/terms/refund')
        mount(Layout, {
            content: <AboutRefund />,
        })
    }
})

Am I doing something dumb here?
