In latest Pimcore 6.4, the pdf preview is not working on grid

Hi All,

In latest Pimcore 6.4, the pdf preview is not working on grid.
It is also not working for other file types like xlsx.

It is working in old Pimcore 6.0 or less.

Steps to reproduce the issue:

  1. create a folder in asset
  2. upload a pdf file
  3. click on the created folder
  4. See the preview in the grid

I tested this in Pimcore 6.4 and Pimcore 6.0.

Is this a bug or do we need to enable some settings in Pimcore 6.4.

thanks
