Panic when using `.collect()` with `ArcSliceMut`

[ARitz-Cracker]

Can't make sense of this...

Though I tried a minimal setup pushing some hard-coded data into a ArcSliceMut<[CompleteTokenInfo]> and it worked fine. Looking at the source code, it seems like the Unsupported error type is only possible if the allocate param of try_reserve_cold is false, yet it seems like the code path of push has it hard-coded to true?
