Why is it OK to ignore the items in this case? If that's not supposed to happen, should we ASSERT?

Yes, we can turn it into assertion

why `= m_impl->currentSize`? I thought the map was empty?

Can we assert that m_impl->currentSize is 0 and then just use `CheckedUint32 newSize;` here?

r=me assuming the bots are happy.

Why did you drop the `RELEASE_ASSERT(m_impl->map.isEmpty());` ?

I feel it'd be good to check that both there is no item in the map and the size is indeed 0.

I thought you mean replacing RELEASE_ASSERT with this... will update.
