Breaking: #88657 - Popup configuration in FormEngine dropped 

See forge#88657

Description 

The options options.popupWindowSize and options.rte.popupWindowSize used to configure popup sizes have been removed.

Impact 

These options are not evaluated anymore.

Affected Installations 

All installations using 3rd party extensions relying on the options are affected.

Migration 

In most cases it's fine to remove the configuration.
