`{@debug}` doesn't work with dynamic block type in `{#if}` if exception is thrown

[space-nuko]

Describe the bug

If I write code like this I expect the data to be printed, but because accessing .missingTypeProp throws an exception it doesn't work.

It's because select_block_type preempts the block creation, which is where the console log is output

However if I replace {@debug} with {(console.log({ item }), '')} it does work

Reproduction

{#each state[id] as item, i}
    {@debug item}
    {#if item.missingTypeProp == "combo"}
        <Combo />
    {:else}
        <OtherWidget />
    {/if}
{/each}
