Steps to reproduce the issue

Update to joomla 4.4.1 or 5.0.1
check extension's language displays

Actual result

Multi line language entries in ini-files cause corrupted display (only language keys are displayed)

System information (as much as possible)

Jooml 4.4.1 or Joomla 5.0.1
php 8.2

Additional comments

If multi-line strings are moved to single line, problem disapears.
I think this is a serious bug e.g. Extensions's displays on backend and frontend are affected and may not fix problem easily.
