Is your feature request related to a problem? Please describe.

Open the template editor
Open a file
The editor is contained within a div id="override-pane" and is only 315px deep
In J3 the equivalent is 43% deeper at 450px

The J4 editor override-pane div is inside another container, the <fieldset class="options-form"> which has - in my view - unneccesary padding of: padding: 1vw 2vw, which takes up valuable width.

Describe the solution you'd like

Increase depth of to 450px deep
Remove the padding from the fieldset container
