TYPO3 Core

I try to use an condition for Including on an MultiDomain Websites different TS for different sites.

<INCLUDE_TYPOSCRIPT: source="FILE:path/to/the/first/domain/main.ts-setup" condition="[PIDinRootline=1]">

now if i go to firstdomain.test the TypoScript is not included. if i go to firstdomain.test/?index.php?id=1 the Typoscript is included correctly. And the Rootpage is Pid = 1
if I Include the file like this:

[PIDinRootline=1]
<INCLUDE_TYPOSCRIPT: source="FILE:path/to/the/first/domain/main.ts-setup">

it works correctly, but with the Problem that i can not use any conditions inside.
