You can see this even in the Webix demo (click “Reload with progress bar”): http://docs.webix.com/samples/19_api/04_progress_data.html
I forgot to mention: this is with the latest download: version 2.2.3
Hello,
Thank you for the bug report. We will fix the bug in the next build.
If you need the solution ASAP, please include the following css in the page with progress bar:
.webix_progress_bottom{
top: auto !important;
}
