TYPO3 Core

In one of my projects (which I'm upgrading from 7 to 9), the customer uses a lot of anchors in longer texts, to enable the visitor to jump back and forth with links in the form of #a-marker-here or #another-marker-there. This is supported by the "anchor" command from CKEditor. Unfortunately TYPO3 always adds an href attribute to it, when saving to or loading from the database, which means, that CKEditor does not recognise it as anchor anymore but as a link.

If the anchor has content (e.g. <a name="special-section">Some special about this</a>) TYPO3 renders a normal link because of the added href. The CKEditor though does not recognise it as an anchor anymore. If the anchor has no content (e.g. <a name="other-important-section"></a>) the link is removed by CKEditor. In the frontend though this is rendered as a link the with current page title as content.

The intended output in the frontend is <a name="some-section">About the project</a>, if I created the anchor with content or <a name="some-section></a> if I created an anchor without content.

Solution: Support anchors without href in HTML parser and typolink function:

Database save/load should not add href
CKEditor should not remove empty anchors
Frontend rendering should not add content to anchors without href

Release: I experienced it with 9.5.5 but from the code, this would be present in master too.
