The changes implemented in T13555: .mw-editsection links should not be part of the <h#> element (see "Heading HTML changes") can be enabled or disabled using the config setting $wgParserEnableLegacyHeadingDOM.
As documented in the release notes at the time, and on that documentaton page, in a future release after they are enabled by default, we should remove that config setting. This is tentatively planned for MediaWiki 1.45.

Can we aim to do this the first week of 1.45? Supporting this is causing some slow down on fixing some editing bugs and web team migrations to Parsoid?
This is blocking MobileFrontend's preparation for Parsoid. Would appreciate it if we could coordinate over next 3 weeks to get this done!
