I took a quick look at your repro, and I'm stumped. Unless I'm missing something really obvious. It does feel like more of a Vue issue than something on our end, possibly related to the fact that you have a slot inside a slot. But that should work afaik.

One workaround is to use scoped slot instead, like so

<tr slot="header" slot-scope="props">

That gets rid of the error.

indeed, this is vue-related.

thank you for the workaround!
