Unable to resize dialog in Safari

This merge request adds a clip-path to the button pane to clip out a notch in the bottom corner to allow the resize handle to be visible.

Just added this to our code base and tested with Safari. Without we are not able to adjust the dialog size. With it, we are now able to adjust the size. Please note we are using MR 55 in addition to this so we are using Drupal 10.3 and there is an issue with dialogs and jQuery which that merge requests fixes.
