TYPO3 Core

Since you seem to have the solution ready, I would like you to provide a patch. I will have a look at it then.

I just changed lines 750 and 751 to disable link generation completely, but this may not be the solution you are looking for:

$sectionTitleLinked = htmlspecialchars($sectionName);

I'm not really familiar with link generator classes / functions of typo3 and xhtml_cleaning mechanism.

The reason for the bug may be eventually that your link does not contain anchor name (only '#' instead of '#name'). Perhaps this hides it from xhtml cleaning (not tested)? Your other links inside browsebar (to link to anchors '#'+md5 of id) work very well and are cleaned out correctly.

It may be useful to modify following function as well since it uses static anchor in code and (in-accessible) javascript, too (don't know if and where it is used):

function makePointerSelector_link

related to #9574 (patch 0009574_v7.patch)

I'd suggest to have a TS property which can turn off linking of section titles:

plugin.tx_indexedsearch.linkSectionTitles

Apart from that a no-brainer imo.
