gridster-item initial position and display values are messing up Gantt Components

[eduarto112]

Hello,
I am using gridster in one project where I had to implement a Gantt Chart inside a gridster-item.
For the chart I started with the Syncfusion Gantt Chart and the problem appeared. After thinking that the problem had to do with the specific component, I tried the DevExtreme Gantt Chart which had the same problem.

I narrowed down the problem to be the position and the display properties set in the gridsterItem.css file.

I am using the version 14.x of the package in the project also in the given example.
