Why In treemap, breadcrumb comes with default random values?

When open treemap with childrens, it bring breadcrumb with default portions. Even if i scroll page width it changes randomly. You can try in here: [https://www.echartsjs.com/examples/en/editor.html?c=treemap-show-parent](url) How can i stop it? When page is rendered i want to see only empty breadcrumb portion(first portion). Is it possible?
