PDF Viewer works as intended (not anymore)

I am viewing my PDF in a popup window and this plugin is the only widget I have so far tested that shows the document without scaling issues.

Two things you should improve:

• The UI lets you define a window width and height for the iframe, but instead of passsing a width attribute, the UI passes a max-width attribute to the iframe, which may lead to the document being displayed small depending on its container.
• Please add vh and vw to define iframe dimensions according to the viewport. I was able to work around that with CSS, but please add it, as it should be low effort.

Thanks.

Edit: I do not know what happened but the current version of the native PDF viewer but it is broken as of now. My page only shows a file download dialogue instead of viewing the PDF in the viewer. Possibly version incompatibility with current WordPress/Elementor.
