BUG: Missing undefined check in user component

[ghost]

this.user?.name cause the getter fetch the undefined this.firstName.slice(0, 11);

user-icon.component.ts

get initials(): string {
   const result = this.user?.name != null ? this.user.name.split(' ') : '  ';
   return result.length > 1 ? `${result[0][0]}${result[1][0]}`.toUpperCase() : '  ';
 }

user.ts

  public get name(): string {
    const fn = this.firstName.slice(0, 11);
    const sn = this.lastName.slice(0, 11);
    const nn = this.nickname && this.nickname.trim() ? ` (${this.nickname.trim().slice(0, 11)})` : '';
    return `${fn} ${sn}${nn}`;
  }

I will fix that in this pull later #661
