This may be a tsup bug? It's shaking and splitting the dts files, but seems to have left only the global declaration from observable-like in its own file, which isn't valid.

Possibly related: egoist/tsup#843; still appears in latest tsup.

To catch these in the future: #31554

Is there a workaround for this besides setting skipLibCheck=true?

[mrginglymus]

I have currently patched out the offending file using yarn so that I can continue to test the rest of the rc.
