Dialog does not stay centered

Problem/Motivation

When pasting a big block of text in the Footnote content editor inside a dialog, the dialog grows, but doesn't stay centered. This can cause the dialog to overflow the viewport width.

Proposed resolution

The MR from #3465020: CKEditor 5 overrides dialogSettings objects provided by CKEditor plugins seems to fix it. Just wanted to log this here in case people are looking for a solution, or in case we want to remove the currently non-functional width: 80% line.
