typolinkCheckRootline serves another purpose (see in TSRef). typolinkEnableLinksAcrossDomains requires typolinkCheckRootline, so it sets it implicitly. typolinkEnableLinksAcrossDomains is used on line 5273 at typo3/sysext/cms/tslib/class.tslib_content.php and later the variable $enableLinksAcrossDomains is used on lines 5461, 5550 and 5518. It is not the case if only typolinkCheckRootline is set. Also RealURl knows about typolinkEnableLinksAcrossDomains and performs different actions depending on its value.

It is respected (lines 5493 and below)

baseURL is not necessary for linking across domains, neither is absRefPrefix.

This was fixed in 4.2. There is a bug report about it. If it does not work, you need to provide steps to reproduce the problem.

I do not understand. Linking in menu using element browser??? How do you do it? menu is typically created by TS and element browser works with RTE.
