Simply put, I interact with an anvil to rename an iron sword, I click on the text field to start renaming it like you normally would but nothing happens, I tried several other items and no matter what I do it seems I can't rename any item using an anvil anymore. I looked at the wiki and nothing I saw mentioned the anvil needing anything more than before to rename items.

Small update, after reading a bit on similar issues, pressing Tab allows me to edit the text field.
