WorldCat identifiers misidentified as LCCN

### Problem

Dear developers,

Thank you for looking into this issue.

### Reproducing the bug

1. Go to https://openlibrary.org/books/add
2. Paste 33294504 in the identifier field.
3. The identifier type is automatically specified as LCCN.

Pasting the WorldCat (https://search.worldcat.org/title/33294504) identifier 33294504 into the identifier field shouldn't make LCCN the identifier type.

### Context

- Browser (Chrome, Safari, Firefox, etc): Chrome
- OS (Windows, Mac, etc): Android
- Logged in (Y/N): Y
- Environment (prod, dev, local): prod
