I really hope somebody can help me out with this: I'm designing a Drupal 8 project and I'm using the built-in CKeditor to edit articles. But the image popup renders outside of screen bounds and I can't find how to fix that. There seems to be no way to influence the top parameter of the dialog.

enter image description here

Thanks a lot!

Im not able to reproduce it on my drupal 8 projects. It might come from your front-end theme. Try to use an administrative theme for edition, like seven.

{yoursite}/admin/appearance At the bottom of the page check use administrative theme for editing.

If the issue doesn't occur anymore on theme seven, you should start by checking in your front-end (custom?) theme for styles on thoses classes :

ui-dialog ui-widget ui-widget-content ui-corner-all ui-front editor-image-dialog ui-dialog--narrow ui-dialog-buttons
