TYPO3 Core

This bug seems to be related to #43668 - but IMHO is a bit different.

There is a problem with the rootline when translation is used and is_siteroot is not set on the root page but somewhere in between the rootline.

- root [1] 
-- starting [2] is_siteroot=1
--- submenue [3]

In the default language i get the rootline "starting <- submenue" but when translation is used, i get the rootline "root <- starting <- submenue". So the menu rendering does not work correct.

When calling TypoScriptFrontendController->updateRootLinesWithTranslations(), $this->tmpl->rootLine has been loaded with the the rootline up to "is_siteroot=1". So the rootline is "starting <- submenue."

But then $this->tmpl->rootLine is overwritten by $this->sys_page->getRootLine() an sets the rootline to "root <- starting <- submenue".

Afaik the check against "is_siteroot" is done in
TYPO3::CMS::Core::TypoScript::TemplateService->processTemplate

Line 686 // If the template record is a Rootlevel record, set the flag and clear the template rootLine (so it starts over from this point)

The solution of Sven Wappler [[http://forge.typo3.org/issues/43668#note-15]] works for us, but i had not tested it with mountpoints f.e. and do not know yet, if it has some sideeffects too.
