This aims to provide better context for translators and make it easier to determine that some strings contain hidden accessibility text and are not displayed in the UI. Props kebbet, mercime, pavelevap, ocean90, swissspidy, Chouby, jipmoors, afercia, desrosj, costdev, audrasjb, SergeyBiryukov. Fixes #29748.
