Sometimes, gerrit-queue will take a random change out of the middle of a chain that's still in-progress, rebase it onto HEAD and try to submit it (which in the case of TVL will often fail, as the build might not succeed due to the parents in the chain missing and then blocking submit).
We don't have a way to reproduce this, it just occasionally happens. Notably, when it happens it seems to occur in clusters - e.g. multiple of these incidents on the same day.
