Adds a proper error when the MDC slider is missing a thumb. Currently we eventually hit a runtime error which isn't easy to debug.

Fixes #24057.

lgtm. It might be a good idea to add a unit test for this since this validation logic is untested, but it's not a big deal if we leave it as is imo

I didn't add one since the other validation logic didn't have test either.
