Linkhandler - access to data outside editors pagetree
With options.pageTree.altElementBrowserMountPoints it is possible to give editors access to pages they don't see in their pagetree.
Something similar should be provided for linkhandler. The configuration pageTreeMountPoints only respects pages/sysfolders with given access to editors.

In the meantime I found out, that TYPO3\CMS\Recordlist\LinkHandler\RecordLinkHandler doesn't respect the TemporaryDbMounts as for example TYPO3\CMS\Recordlist\LinkHandler\PageLinkHandler does.
Adding $this->setTemporaryDbMounts(); within function render(...) solves the problem.
