Layout card configuration popup width

Hello everyone,
I have a question that I was unfortunately unable to answer through research in the forum.
I use a custom:layout-card in the dashboard (in panel mode), which contains all the cards of the dashboard.
When you edit this card, the popup “layout card configuration” opens. Unfortunately, this popup does not use the entire width of the window, but about half of it. Configuring is unnecessarily cumbersome because you have to keep scrolling even though the screen is large enough.
I have already been able to determine with the browser tools that it is the “mdc-dialog__surface” class that contains the information, but so far I have not been able to set this setting permanently.

It is NOT the card width of the layout cards themselves but the width of the configuration popup.

Does anyone have any advice on where to set this setting and how?
