Flow input interface issue with the File picker and/or Flow Trigger Bundle's trigger flow field.

[br41nslug]

Describe the Bug

For the flows triggered from content panel, directus has several type of input that takes information in advance.
We are able to design what kind of input required flawlessly until we need to add image or any file as an input.
The JSON type allow us to pick relational data therefore it seems like Files could be used with it.

When i click on the trigger in the right panel it works as expected.

Unfortunately when i click the trigger in the content/fields panel (with the help of this extension : "Flow Trigger Bundle") the UI does not allow us as it can be seen in the snapshow below :

I created the issue here because the extension does not have any related repo for itself.

Thank you.

To Reproduce

1. Create a flow that can be triggered from content space and add a json typed field to make it pick a file as an input.
2. Install "Flow Trigger Bundle" extension and add a flow trigger field in your collection.
3. Trigger the flow exists in the content creation area.

The issue seems like z-index problem.
The dialog window has "keep-behind" class which applies "z-index:500" when we trigger it from panel.
The dialog window hasn't "keep-behind" class thus it's index remains "z-index:600" when we trigger it from fields/interface.

Only difference between trigger that the panel does not have ':disabled="getButtonDisabled(trigger)"' while the interface has in the trigger function.
