Does this area need the same fix for not adjusting base mesh positions when sculpting a shape key?

From my testing, no, I wasn't able to encounter a situation where this was needed. Since we restore from the unode positions, I don't think we would need to selectively filter that above on line 1515

To add to this - I think we could filter out some of these applications if we know we're working with non-basis shape keys, but I don't know if the potential speed gain would be worth the extra logic there

I'd keep apply_translations_to_dependent_shape_keys inlined here, I think it makes this change harder to read and it's not really a separate thing from changing the active shape key conceptually

Sometimes it's useful to just get a stack trace of nullptr than open msvc so get a handling of an exception..\

Ah, yeah, I missed removing this, I don't think it does much in this particular case.
