Gantt Marker disappears when the data is reloaded

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

Is this expected behavior? I am using version 5.27

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

gantt.init("container name");

Please, reproduce the issue in the snippet:
Then click on the “Share” button and copy the link.

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