Gantt Marker disappears when the data is reloaded

Gantt
#1

As the title says “Gantt Marker disappears when the data is reloaded.”

Is this expected behavior? I am using version 5.27

#2

Hello Nikolai,
Unfortunately, I couldn’t reproduce the issue with the 5.2.7 version. I tried the following commands:

gantt.parse(data);
gantt.load('URL');
gantt.init("container name");

Please, reproduce the issue in the snippet:

Or give me the steps to reproduce the issue and details about your configuration and commands.
