Describe the Bug

Document previews in the Context Chat search UI covers up most of the screen instead of being displayed below the title of the document in a list fashion.

Expected Behavior

from NC 34 with the same assistant 3.5.0-dev.1 in the local machine so it might be something changed in NC 35 but not sure.

To Reproduce

1. open Assistant modal
2. navigate to the Context Chat -> Context Chat search tab
3. enter a query and press "Context Chat search"

In which preview is this opening? Can this be a Euro-Office issue?

[kyteinsky]

It's a PDF file.
The render is from files_pdfviewer.

https://cloud.example.com/apps/files_pdfviewer/?file=https%3A%2F%2Fcloud.example.com%2Fremote.php%2Fdav%2Ffiles%2Fanupam%2F%2FAssistant%2F1752626654-85884.pdf

Can this be a Euro-Office issue?

Not sure, looks more like files_pdfviewer alone might be doing this.
weirdly enough, normal PDFs opened from Files app don't use it, they use Euro-Office to render the PDF.

Potential solution: style the iFrame: width stays, height can be fixed, remove top and position absolute
