zsh completion: compadd strings with hyphens and spaces

Question

This command works:
compadd - '-test1 text' '-test1 qwer'

This command works too:
compadd -Q - '-test1 text' '-test2 qwer'

But if first words are the same, then the command does not works:
compadd -Q - '-test1 text' '-test1 qwer'

How can I fix it?

Answer 1

Better late than never, huh?

compadd -Q - '-test1\ text' '-test1\ qwer'
