How can I refresh the macOS dictionary?

Consider the following workflow: 1. Open TextEdit. 2. Type a word that's not in the dictionary. 3. Right-click on that word and select 'Learn Spelling'. 4. Observe the squiggly underline disappears, as the word is now recognised. 5. Observe the word is added to the ~/Spelling/LocalDictionary file. 6. Quit TextEdit. 7. Remove the word from the ~/Spelling/LocalDictionary file. 8. Reopen TextEdit. 9. Type the same word again. 10. Observe it is *still* recognised (not squiggly-underlined), despite no longer being in the local dictionary. It seems the problem here is that there is some sort of cache maintained by macOS that is not refreshed. If I right-click on the word in TextEdit to remove it from the local dictionary instead of editing the file, it is indeed no longer recognised; i.e., this appears to update the cache. Is there any way I can manually refresh the cache of local dictionary words?
