Breaking: #72888 - Removed HtmlParser mapTags functionality

See Issue #72888

Description

The functionality to map tags explicitly from the HtmlParser code has been removed:

• HtmlParser::mapTags()
• RteHtmlParser::defaultTStagMapping()

Impact

Calling one of the two methods above will result in a PHP fatal error.

Affected Installations

Any installation using custom RTE transformation and wanting to remap tags while parsing HTML.

Migration

Use the “remap” functionality of the keepTags logic within HtmlParser to achieve the same in custom transformations.
