Deprecation: #80076 - TypoScript option page.insertClassesFromRTE

See Issue #80076

Description

The TypoScript setting page.insertClassesFromRTE has been marked as deprecated.

The option enabled loading of CSS classes defined by backend PageTs config RTE.classes as inline CSS into a frontend page. However it did not take merged RTE options and userTS/pageTS overrides into account.

Impact

Setting page.insertClassesFromRTE in TypoScript will trigger a deprecation log entry.

Affected Installations

Any installation having the option activated in TypoScript.

Migration

In order to separate the functionality, all CSS classes which have been used in the RTE should be defined separately for the frontend rendering in a custom CSS/LESS/SASS file.
