Extracting multiple archives in one command with 7z yields "No files to process"

Extracting multiple files with 7z effectively fails. Individually the archives extract without errors. I don't do this very often but my memory and searches indicate that 7z x *.rar -o* *should* work. Same behavior with version 25.01 and the e command.

~/
❯ 7z x *.rar
