Compose version: 1.7.0-SNAPSHOT ConstraintLayout version: 1.0.1 (it seems to not be an issue when using 1.1.0-alpha13)

When wrapping ConstraintLayout in Compose with SharedTransitionLayout, the following crash is observed, will the 1.1.0-alpha13 be released soon?

java.lang.IllegalStateException: Error: Placement happened before lookahead.

I simpler example would be appreciated. I tried to download the pull request and build it but it relies on, for example, `rustc` to be installed which I don't have installed on my compose development machine.

Does the program work without the compiler switch. That is, is `"-P", "plugin:androidx.compose.compiler.plugins.kotlin:experimentalStrongSkipping=true",` required to reproduce or is just changing the runtime enough?

Marked as fixed.

Yeah, changing compiler switch(enable/disable StrongSkipping, enable/disable nonSkippingGroup) has no effect, only changing runtime make sense.
Sorry for that, I will try to extract an example when I'm free.
