Bootstrap4 Collaspse Component with media preview not working well

[jgnan]

Hi,

I found if I use Bootstrap4 Collapse component with the latest FilePond(4.40.3) and media preview plugin(1.0.11), using no matter the files parameter of the FilePond's constructor or addFiles/addFile method, it will show nothing in the preview area until the collapse component shown the FilePond widget. But actually after my research it do added the files, as the file input element is created within the widget.

To redo this, just using the official media preview demo with bootstrap4 Collapse, and draw the widget within one collapsed tag, set some media file to it, you can reproduce the issue.

I'd already find a work around to init the widget only when the collapse show, so just to inform you about this issue, it is not a serious problem to me. Hope can make media preview better.

Best regards
